Anthony Horowitz: The House of Silk

So why do I take up my pen one final time to stir up memories which might better be forgotten? Perhaps my reasons are selfish. It could be that, like so many old men with their lives behind them, I am seeking some sort of solace. The nurses who attend upon me assure me that writing is therapeutic and will prevent me from falling into the moods to which I am sometimes inclined. But there is another reason, too.

The adventures of The Man in the Flat Cap and The House of Silk were, in some respects, the most sensational of Sherlock Holmes’s career but at the time it was impossible for me to tell them, for reasons that will become abundantly clear. The fact that they became inextricably tangled up, the one with the other, meant that they could not be separated. And yet it has always been my desire to set them down, to complete the Holmes canon. In this I am like a chemist in pursuit of a formula, or perhaps a collector of rare stamps who cannot take full pride in his catalogue knowing there to be two or three specimens that have evaded his grasp. I cannot prevent myself. It must be done.

It was impossible before — and I am not just referring to Holmes’s well-known aversion to publicity. No, the events which I am about to describe were simply too monstrous, too shocking to appear in print. They still are. It is no exaggeration to suggest that they would tear apart the entire fabric of society and, particularly at a time of war, this is something I cannot risk. When I am done, assuming I have the strength for the task, I will have this manuscript packed up and sent to the vaults of Cox and Co. in Charing Cross, where certain others of my private papers are stored. I will give instructions that for one hundred years, the packet must not be opened. It is impossible to imagine what the world will be like then, what advances mankind will have made, but perhaps future readers will be more inured to scandal and corruption than my own would have been. To them I bequeath one last portrait of Mr Sherlock Holmes, and a perspective that has not been seen before.

But I have wasted enough energy on my own preoccupations. I should have already opened the door of 221B Baker Street and entered the room where so many adventures began. I see it now, the glow of the lamp behind the glass and the seventeen steps beckoning me up from the street. How far away they seem, how long ago since last I was there. Yes. There he is, with pipe in hand. He turns to me. He smiles. ‘The game’s afoot…’

‘Influenza is unpleasant,’ Sherlock Holmes remarked, ‘but you are right in thinking that, with your wife’s help, the child will recover soon.’

‘I very much hope so,’ I replied, then stopped and gazed at him in wide-eyed astonishment. My tea had been halfway to my lips but I returned it to the table with such force that the cup and the saucer almost parted company. ‘But for Heaven’s sake, Holmes!’ I exclaimed. ‘You have taken the very thoughts from my head. I swear I have not uttered a word about the child nor his illness. You know that my wife is away — that much you might have deduced from my presence here. But I have not yet mentioned to you the reason for her absence and I am certain that there has been nothing in my behaviour that could have given you any clue.’

It was in the last days of November, the year 1890, when this exchange took place. London was in the grip of a merciless winter, the streets so cold that the very gas lamps seemed frozen solid and what little light they gave out subsumed by the endless fog. Outside, people drifted along the pavements like ghosts, with their heads bowed and their faces covered, while the growlers rattled past, their horses anxious to be home. And I was glad to be in, with a fire blazing in the hearth, the familiar smell of tobacco in the air and — for all the clutter and chaos with which my friend chose to surround himself — a sense that everything was in its right place.

I had telegraphed my intention to take up my old room and stay with Holmes for a short while, and I had been delighted to receive his acquiescence by return. My practice could manage without me. I was temporarily alone. And I had it in mind to watch over my friend until I was certain that he was fully restored to health. For Holmes had deliberately starved himself for three days and three nights, taking neither food nor water, in order to persuade a particularly cruel and vengeful adversary that he was close to death. The ruse had succeeded triumphantly, and the man was now in the capable hands of Inspector Morton of the Yard. But I was still concerned about the strain that Holmes had placed upon himself and thought it advisable to keep an eye on him until his metabolism was fully restored.

I was therefore glad to see him enjoying a large plate of scones with violet honey and cream, along with a pound cake and tea, all of which Mrs Hudson had carried in on a tray and served for the two of us. Holmes did seem to be on the mend, lying at ease in his big armchair, wearing his dressing gown and with his feet stretched out in front of the fire. He had always been of a distinctly lean and even cadaverous physique, those sharp eyes accentuated by his aquiline nose, but at least there was some colour in his skin and everything about his voice and manner pronounced him to be very much his old self.

He had greeted me warmly, and as I took my place opposite him, I felt the strange sensation that I was awakening from a dream. It was as if the last two years had never happened, that I had never met my beloved Mary, married her and moved to our home in Kensington, purchased with the proceeds of the Agra pearls. I could have still been a bachelor, living here with Holmes, sharing with him the excitement of the chase and the unravelling of yet another mystery.

And it occurred to me that he might well have preferred it thus. Holmes spoke seldom about my domestic arrangements. He had been abroad at the time of my wedding and it had occurred to me then that it might not have been entirely a coincidence. It would be unfair to say that the entire subject of my marriage was forbidden, but there was an unspoken agreement that we would not discuss it at any length. My happiness and contentment were evident to Holmes, and he was generous enough not to begrudge it. When I had first arrived, he had asked after Mrs Watson. But he had not requested any further information and I had certainly provided none, making his remarks all the more unfathomable.

‘You look at me as if I were a conjuror,’ Holmes remarked, with a laugh. ‘I take it you have given up on the works of Edgar Allen Poe?’

‘You mean his detective, Dupin?’ I said.

‘He used a method which he termed ratiocination. In his view, it was possible to read a person’s innermost thoughts without their even needing to speak. It could all be done from a simple study of their movements, by the very flicker of an eyebrow. The idea impressed me greatly at the time but I seem to recall that you were somewhat scornful—’

‘And doubtless I will pay for it now,’ I concurred. ‘But are you seriously telling me, Holmes, that you could deduce the sickness of a child you have never met, simply from my behaviour over a plate of scones?’

‘That and rather more,’ Holmes replied. ‘I can tell that you have just returned from Holborn Viaduct. That you left your house in a hurry, but even so missed the train. Perhaps the fact that you are currently without a servant girl is to blame.’

‘No, Holmes!’ I cried. ‘I will not have it!’

‘I am wrong?’

‘No. You are correct on every count. But how is it possible…?’

‘It is a simple matter of observation and deduction, the one informing the other. Were I to explain it to you, it would all seem painfully childish.’
