“Don't count on seeing Major Mordaunt for a day or two, Mr Holmes,” said Truscott morosely, stamping his feet and rubbing his hands as the boat was hauled in. “You can't drag a lake bottom as steep as that one. Best let him pop up of his own accord. They all do so, sooner or later, once the gas starts to lift them. It won't do for the coroner, though. That's the difficulty.”
He walked off towards Sergeant Acott, presumably for the satisfaction of repeating to him what he had just said to us.
I had not seen Alfred Swain for more than an hour. He was no doubt in conference with the local coroner. A gravelly-bearded man in a dark suit, driving a horse and trap, certainly had the appearance of an officer of the court.
An inquest could come to only one conclusion. If ever there was a case of justifiable homicide I supposed it must be this. Mordaunt had proved himself an experienced shot, even in the half-light. His first aim had missed Sherlock Holmes by only a few inches. He had been given two chances to lay down his revolver and had declined both. Without Swain's presence of mind and unexpected marksmanship, my friend would have stood no more chance against the second bullet than a duck in a shooting gallery.
It transpired that Alfred Swain was the only man to have drawn a firearmâand the last whom I expected to be carrying one. At eleven o'clock that morning he reappeared at last, riding a grey mare. Behind him a farm wagon carried a boat not much larger than Mordaunt's but somewhat more sturdy. Such craft were generally on call to country police forces for use in rivers and reservoirs. The consequence was that each force had to take what it could get.
Two long planks were drawn down from the tail of the wagon to the mud of the bank.
“Mr Holmes!”
“Mr Swain?”
Swain walked closer.
“We can cross to the island, sir, if you would care to go. Before the county sheriff and others get here, perhaps youâand Dr Watson, if he wishesâwould like to see for yourselves.”
“Major Mordaunt's private kingdom?”
“If you were to do it, Mr Holmes, I think it had best be done without further delay.”
In plain English, once Superintendent Truscott's guests arrived from Abbots Langley we should have as much chance of investigating the pleasure island as Adam and Eve had of returning to Paradise. What debt from the past did Alfred Swain owe to Sherlock Holmes that it should be repaid so amply now?
“There are boots on the wagon, gentlemen.”
We sat on a felled tree trunk and pulled our waders on. Our ferry boat was in the water. Supported by constables at either arm, we edged down a slippery plank and clambered over the stern of the hull. Swain took the opposite seat as oarsman in the bows.
The inspector was a quiet man by nature, son of a Dorset village schoolmaster, as Holmes later told me. It was still hard to say whether he was shocked or serene in the aftermath of Mordaunt's death. As we were crossing the calm lake, he spoke softlyâto us or to himself.
“What possessed him to stand up in the boat? Surely he knew he would swamp it!”
It seemed to me an eminently sensible comment, but that was all by way of conversation until we reached the island shore. We waded across some fifteen feet of mud before coming to a crude plank slipway. I thought that a man who brought a woman here would probably have to carry her ashore, establishing an intimacy from the first step. However, if anyone had been here for many months, there was little sign of it. A path had been trodden long before between laurel bushes and yew but the banks of brambles and nettles in flower were now badly in need of clearing.
The so-called Temple of Proserpine was no more than a few minutes' walk from the water. With its single gable, it suggested a garden bungalow on an Indian tea plantation. Shutters were locked over the glass panels of its two double doors and there was a fixed window at either side of them. It might very well have served as a cricket pavilion, its front quite forty feet wide. Most of the original top coat of white paint had peeled away, leaving a cream undercoat with patches of bare, silvered wood.
Such was Mordaunt's rendezvous with his female companions. Perhaps it was also a conveniently secret spot where he met Peter Quint to trade gold for bank-notes. So long as he had the only key to the shed where the oars were kept, he was master of either situation. This lawn was where Miss Temple had first seen Maria Jessel. I thought how easily a tragic boating accident might have been arranged for Miles and his governess as they wooed their ghosts!
Swain made no objection when Holmes opened his useful pocket-knife to deal with the lock. Then he drew apart the shutters and opened the glass doors. Dappled sunlight through the glass revealed a dilapidated lounge equipped with bamboo furniture and scattered cushions. It was flanked by two smaller rooms on each side. The whole place was a tribute to the colonial tropics, familiar to three generations of the Mordaunt family. Against the far wall stood an upright Broadwood piano in tortoise-shell lacquer, no doubt a memento of lanterns, parties and music on summer evenings! Holmes touched the keyboard casually. Half of the notes were now dumb and several of them sank down, never to rise. It had served no purpose for many years.
“One hesitates to condemn any musical instrument as beyond saving,” said my friend casually, “yet I fear this must be so.”
Before I could say that Mordaunt should have jumped at the chance to have the wreck dismantled and removed on the cattle raft, as Mrs Grose described it, my companions moved on.
A smaller room with two wall-mirrors and a miniature dressing-table had presumably been set apart for female guests. Another, on the far side, had a leather chair and a tableâperhaps this was the counting house where Mordaunt and Quint exchanged coins for bank-notes. A shelf in the adjoining room held a flame-darkened primus stove and rusted tins labelled for tea, sugar and coffee. Holmes made a little routine of opening the drawers in the furniture and closing them without finding anything of interest. Or so it seemed. Standing in the mirrored room with his back to Swain, he “palmed” a small bottle from the dressing-table drawer. It had a cosmetic or theatrical look about it.
I could not see that there was anything here for us. Only the broken-down piano, retained for no obvious use, seemed worth my friend's inspection. Holmes stooped and used his pocket-knife blade to loosen a screw under the keyboard so that the pedal-board might be lifted out. This revealed only the iron frame with its strings and the pedal mechanism. Straightening up and lifting the top, Holmes then peered down into the musty space of felted hammers and treble wire. Shaking his head, he closed the lid and turned away.
As though it were a last resort, he dropped down on one knee and unfolded his pocket magnifying-glass to examine the wooden floorboards just in front of the two foremost casters.
“Most curious,” he said quietly, folding the glass and returning it to his watch-pocket. “Unless the instrument is lifted a little, the weight on the casters is bound to mark floorboards of softwood timber as it is moved over them. In this case, it seems that the right-hand caster alone has been moved repeatedly in a brief arc. Put more simply, someone who had no companion to help him lift the weight from the boards has had to pull the right-hand side of the piano from the wall on numerous occasions. Two men would have been able to lift it clear of the boards. Why did he always do this aloneâand so often? It is a small matter but well worth our attention. This particular model of the Messrs Broadwood has a very substantial iron frame. Perhaps, Mr Swain, you would be kind enough to assist me.”
The inspector eased his right arm and the edge of his shoulder into the narrow gap between the back of the tall piano and the wall.
“You will find, Mr Swain that there is a hand-hold about halfway down. I shall lift from under the keyboard.”
Holmes drew the piano carefully forward. The floorboards at the far end groaned as the left-hand brass casters ground into them. A few seconds later the right-hand end of the upright piano was at a slight angle to the wall, revealing the back of the instrument.
The structure was not solid, as I had supposed. A fine wire mesh on a wooden frame fitted into the back of the instrument and was screwed into place. It required only the loosening of half a dozen screws to remove it. This was done easily with the edge of a penny coin.
Once the mesh on its frame was lifted out, I doubt whether, even among pianists, many knew that their instruments had a concealed recess below the strings. It was large enough to hold a book or even a small painting, though its original intention was presumably to house furniture polish, dusters, methylated spirits and all the essential cleaning materials for rosewood, brass, ivory and ebony.
When I saw what lay in this recess I knew we were on the right road, though I could not yet tell where it led! It was a large steel key. Only the man who put it there would ever have looked for it in such a place or even have known that such a recess existed. It was plain at a glance that the key did not fit any door or item of furniture around us. In the first place, it was too old.
I guessed that it had not been made in the last forty years. It was about four inches long, the oval of its handle decorated with filigree work of mid-century. Holmes held it in his hand and intoned two lines from his store of street literature.
“My name is Chubb, that makes the Patent Locks;
Look on my works, ye burglars, and despair.”
Then he gazed about him.
“Up there, I think,” he said presently. “There is nothing down here worthy of it.”
An inspection-trap was recessed in the centre of the main ceiling, giving access to a loft or roof-space. It seemed the only place where there might be a lock to match the key. Holmes stared at it.
“A curiosity of the deviant mind, Mr Swain, is that a man who works to frustrate detection invariably draws his pursuer onto a trail pointing the way he has gone. As if the poor devil wanted to be caught.”
“I can't see that here, Mr Holmes.”
“Can you not, Mr Swain? Of the garden sheds, only one was locked. How could it fail to attract interest? It contained a pair of sculls. Had it not been locked, they might not have signified. The need to make the only boat unusable by all but one person gave them importance. No one could cross to the island without Mordaunt's authority. On our arrival here, what do we find? A piano whose voice is defunct, which might have been removed on several occasions but was kept here by his orders on at least one occasion. The damage to the floorboard indicates that the only function of the poor voiceless instrument was to be moved to and fro at frequent intervals, making the right-hand side of its back accessible. It beckons the investigator to that hiding place behind the covering of metal gauze.”
“But if you are correct, Mr Holmesâ”
“I am, Mr Swain. One more thing, however. No matter how thoroughly this room might be searched, the piano with its iron frame could be moved only by someone with sufficient strength.”
“Excluding Maria Jessel and, for that matter, Victoria Temple,” I said suddenly.
“Precisely. Now, if you please, gentlemen, there remains the inspection hatch.”
“We had best proceed quickly, sir.” Swain glanced at the window, as if expecting Superintendent Truscott's shadow to fall across it. “I can hold you standing on my shoulders if you can balance there, Mr Holmes. You could easily reach the ledge of the hatch. I am a little younger and therefore can bear your weight easily.”
“Younger, and therefore had better stand on my shoulders,” said Holmes peremptorily. “The greater strength will be needed in pulling up through the hatch.”
“As you wish, sir.”
With a balance that might have graced a circus acrobat, Swain crouched on my friend's back in stocking'd feet as Holmes straightened up. The inspector's soles and heels moulded themselves to the changing posture until he had only to lift his hands and push the white-painted trap aside. He pulled himself up and slid into the roof-space.
“A main beam and a rope attached to it, Mr Holmes. He probably pushed the trap up with a pole and hooked the rope down. He might nudge it closed afterwards and take the pole with him. Stand away a little, if you please.”
A length of knotted rope swung down, hanging level with our knees. It was a simple device that every scouting party in rough terrain would be familiar with. In my training for Afghanistan, I should have thought nothing of climbing it. Now I was not so sure.
Holmes stepped in front of me.
“Wait a bit, Watson!”
He took the rope between his hands, locked his feet on the lowest section and swarmed up as if he had done nothing else all his life. I followed, standing on the knot and holding as high as I could.
“Grip tight and hold, sir,” said Swain quietly. Then I was guided by either arm to the safe flooring of the attic. Light through a rear dormer window was quite enough for our investigation.
Disused garden furniture made up the lumber, except for a military travelling chest of dark, varnished elm. This was some four feet long by two feet wide and eighteen inches deep. Its dark lacquer was scratched and worn, as if from campaigning. At the centre of the lid, in a scroll of dim red letters, I read “J. Mordaunt, M.D., Netley.” How well I knew that design! It was almost a twin to the one which accompanied me to Netley barracks as a newly-qualified physician beginning my regimental training, twenty years before.
Holmes was on his knees, inspecting the keyhole with its old-fashioned ornamental plate. It was surely a match for the key. My friend scrutinised the floorboards at the front of the box.
“No one has opened this for some months. Possibly not since Miss Temple's trial.”
“You are sure?” I asked.
“Once the poor young woman was locked away in Broad-moor, believing gratefully that Mordaunt had saved her from the gallows, the evidence ceased to matter to him. See here. There is an infestation of woodwormâfurniture beetleâin the rim of the lid. The eggs are laid in existing holes by the adult beetle during the autumn, usually in September. The larvae eat their way out in the springâApril or May, as a rule. The powderâthe frassâis undisturbed in this case. Mordaunt thought he had all the time in the world. That was very nearly the truth. Casual neglect of this sortâpostponing the destruction of evidenceâhas proved fatal even to some of the great criminal minds. Mordaunt was not remotely of that first rank.”
