serious, you would surely have insisted upon attending yourself.’
‘Your reasoning has so far been utterly straightforward in every respect,’ I said. ‘But it does not explain how you knew that my thoughts had turned towards them at that precise moment.’
‘You will forgive me if I say that you are to me as an open book, my dear Watson, and that with every movement, you turn another page. As you sat there sipping your tea, I noticed your eye drift towards the newspaper on the table right beside you. You glanced at the headline and then reached out and turned it face down. Why? It was perhaps the report on the train crash at Norton Fitzwarren a few weeks ago that disturbed you. The first findings of the investigation into the deaths of ten passengers were published today and it was, of course, the last thing you would wish to read just after leaving your wife at a station.’
‘That did indeed remind me of her journey,’ I agreed. ‘But the sickness of the child?’
‘From the newspaper, your attention turned to the patch of carpet beside the desk and I distinctly saw you smile to yourself. It was there, of course, that you once kept your medicine bag and it was surely that association that reminded you of the reason for your wife’s visit.’
‘This is all guesswork, Holmes,’ I insisted. ‘You say Holborn Viaduct, for example. It could have been any station in London.
‘You know that I deplore guesswork. It is sometimes necessary to connect points of evidence with the use of imagination, but that is not at all the same thing. Mrs Forrester lives in Camberwell. The London Chatham and Dover Railway has regular departures from Holborn Viaduct. I would have considered that the logical starting point, even if you had not obliged me by leaving your own suitcase by the door. From where I am sitting, I can clearly see a label from the Holborn Viaduct Left Luggage Office attached to the handle.’
‘And the rest of it?
‘The fact that you have lost your maid and that you left the house in a hurry? The smudge of black polish on the side of your left cuff clearly indicates both. You cleaned your own shoes and you did so rather carelessly. Moreover, in your haste, you forgot your gloves—’
‘Mrs Hudson took my coat from me. She could also have taken my gloves.’
‘In which case, when we shook hands, why would yours have been so cold? No, Watson, your entire bearing speaks of disorganisation and disarray.’
‘Everything you say is right,’ I admitted. ‘But one last mystery, Holmes. How can you be so sure that my wife missed her train?’
‘As soon as you arrived, I noticed a strong scent of coffee on your clothes. Why would you be drinking coffee immediately before coming to me for tea? The inference is that you missed your train and were forced to stay with your wife for longer than you had intended. You stowed your case at the left luggage office and went with her to a coffee house. Might it have been Lockhart’s? I’m told the coffee there is particularly good.’
There was a short silence and then I burst into laughter. ‘Well, Holmes,’ I said. ‘I can see that I had no reason to worry about your health. You are as remarkable as ever.’
‘It was quite elementary,’ returned the detective with a languid gesture of one hand. ‘But perhaps something of greater interest now approaches. Unless I am mistaken, that is the front door …’
Sure enough, Mrs Hudson came in once again, this time ushering in a man who walked into the room as if he were making an entrance on the London stage. He was formally dressed in a dark tail coat, wing collar and white bow tie with a black cloak around his shoulders, waistcoat, gloves and patent leather shoes. In one hand he held a pair of white gloves and in the other a rosewood walking stick with a silver tip and handle. His dark hair was surprisingly long, sweeping back over a high forehead and he had neither beard nor moustache. His skin was pale,
