changing surfaces beneath the wheels, even the direction of the wind rattling against the windows — and drawn a perfectly detailed map of our journey at the end of it. But I was most certainly not up to the challenge and could only wait for the glow of gas lamps to reassure me that we were back in the city and, perhaps half an hour later, the slowing down of the horses and the final, jolting halt that signalled we were at the end of our journey. Sure enough, Underwood threw open the door and there, across the road, were my familiar lodgings.
‘Safely home, Dr Watson,’ said he. ‘I apologise once again for inconveniencing you.’
‘I will not forget you easily, Mr Underwood,’ I replied.
He raised his eyebrows. ‘My master has told you my name? How curious.’
‘Perhaps you would care to tell me his.’
‘Oh no, sir. I concede that I am but a speck on a canvas. My life is of little significance in comparison with his greatness but nonetheless I am attached to it and would wish it to continue for a while yet. I will wish you a good night.’
I climbed down. He signalled to the driver and I watched as the carriage rattled away, then hurried in.
But there was to be no rest for me that night. I had already begun to formulate a plan by which the key might safely be delivered to Holmes, along with a message alerting him to the danger he was in even if, as I feared, I was not permitted to visit him myself. I had already concluded that a straightforward letter would do no good. Our enemies were all around us and there was every chance that they would intercept it. If they discovered that I was aware of their intentions, it might spur them on to strike all the faster. But I could still send him a message — and some sort of code was required. The question was, how could I indicate that it was there to be deciphered? There was also the key. How could I deliver it into his hand? And then, casting my eye around the room, I fell upon the answer: the very same book that Holmes and I had been discussing only a few days before,
The volume was leather-bound and quite thick. Upon examining it, I saw that it would be possible to slip the key into the space between the spine and the bound edges of the pages. This I did and, taking up the candle, I carefully poured liquid wax into the two ends, in effect gluing it in place. The book still opened normally and there was nothing to suggest that it had been tampered with. Taking up my pen, I then wrote the name, Sherlock Holmes, on the frontispiece and, beneath it, an address: 122b Baker Street. To a casual observer it would appear that nothing was amiss but Holmes would recognise my hand at once and would see that the number of our lodgings had been inverted. Finally, I turned to page 122 and, using a pencil, placed a series of tiny dots, almost invisible to the naked eye, under certain letters in the text so that a new message was spelled out: YOU ARE IN GREAT DANGER. THEY PLAN TO KILL YOU. USE KEY TO CELL. I AM WAITING. JW.
Satisfied with my work, I finally went to bed and fell into a troubled sleep punctured by images of the girl, Sally, lying in the street with blood all around her, of a length of white ribbon looped around a dead boy’s wrist and of the man with the high-domed forehead, looming at me across the refectory table.
I awoke early the next day and sent a message to Lestrade, urging him once again to help arrange a visit to Holloway, no matter what Inspector Harriman had to say. To my surprise, I received a reply informing me that I could enter the prison at three o’clock that afternoon, that Harriman had concluded his preliminary investigation and that the coronor’s court had indeed been set for Thursday, two days hence. On first reading, this struck me as good news. But then I was struck by a more sinister explanation. If Harriman was part of the conspiracy, as Holmes believed and as everything about his manner and even his appearance suggested, he might well have stood aside for a quite different reason. My host of the night before had insisted that Holmes would never be allowed to stand trial. Suppose the assassins were preparing to strike! Could Harriman know that it was already too late?
I could barely contain myself throughout the morning and left Baker Street well before the appointed hour, arriving at Camden Road before the clocks had struck the half-hour. The coachman left me in front of the outer gate and, despite my protestations, hurried away, leaving me in the cold and misty air. All in all I couldn’t blame him. This wasn’t a place where any Christian soul would have chosen to linger.
The prison was of Gothic design; on first appearance a sprawling, ominous castle, perhaps something out of a fairy story written for a malevolent child. Constructed from Kentish ragstone, it consisted of a series of turrets and chimneys, flagpoles and castellated walls, with a single tower soaring above and seeming almost to disappear into the clouds. A rough, muddy track led to the main entrance, which was purposefully designed to be as unwelcoming as possible, with a massive wooden gate and steel portcullis framed by a few bare and withered trees on either side. A brick wall, at least fifteen feet high, surrounded the entire complex, but above it I could make out one of the wings, with two lines of small, barred windows whose rigid uniformity somehow hinted at the emptiness and misery of life inside. The prison had been built at the foot of a hill and, looking beyond it, it was possible to make out the pleasant pastures and slopes that rose up to Highgate. But that was another world, as if the wrong backdrop had been accidentally lowered onto the stage. Holloway Prison stood on the site of a former cemetery, and the whiff of death and decay still clung to the place, damning those who were inside, warning those without to stay away.
It was as much as I could bear to wait thirty minutes in the dismal light with my breath frosting and the cold spreading upwards through my feet. At last I walked forward, clutching the book with the key concealed in its spine, and as I entered the prison it occurred to me that were I to be discovered, this horrid place could well become my home. I think it is true to say that I broke the law at least three times in the company of Sherlock Holmes, always for the best of reasons, but this was the high point of my criminal career. Strangely, I was not even slightly nervous. It did not occur to me that anything could possibly go wrong. All my thoughts were focused on the plight of my friend.
I knocked on a door which stood inconspicuously beside the outer gate and it was opened almost at once by a surprisingly bluff and even jovial officer, dressed in dark blue tunic and trousers with a bunch of keys hanging from a wide, leather belt. ‘Come in, sir. Come in. It’s more pleasant in than out and there’s not many days you could say
We had entered a corridor with an open door to one side, and it was through here that I was taken, into a small room with a desk, two chairs and a single window looking directly on to a brick wall. To one side stood a cabinet with perhaps fifty keys suspended on hooks. A large clock faced me and I noticed the second hand moved ponderously, pausing between each movement, as if to emphasise the slow passage of time for all those who had come this way. A man sat beneath it. He was dressed similarly to the officer who had met me, but his uniform had a few trimmings of gold, on his cap and shoulders, denoting his senior rank. He was elderly, with grey hair cut short and steely eyes. As he saw me, he scrambled to his feet and came round from behind the desk.
‘Dr Watson?’
‘Yes.’
‘My name is Hawkins. I am the chief warder. You have come to see Mr Sherlock Holmes?’
‘Yes.’ I uttered the word with a sudden sense of dread.
‘I am sorry to have to inform you that he was taken ill this morning. I can assure you that we have done everything we can to accommodate him in a manner appropriate to a man of his distinction, despite the very serious crimes of which he is accused. He has been kept away from the other prisoners. I have personally visited him on several occasions and have had the pleasure of conversing with him. His illness came suddenly and he was given treatment at once.’
‘What is wrong with him?’
‘We have no idea. He took his lunch at eleven o’clock and rang the bell for assistance immediately after. My officers found him doubled up on the floor of his cell in evident pain.’
I felt an ice-cold tremor in the very depth of my heart. It was exactly what I had been fearing. ‘Where is he now?’ I asked.
‘He is in the infirmary. Our medical officer, Dr Trevelyan, has a number of private rooms which he reserves for desperate cases. After examining Mr Holmes, he insisted on moving him there.’
