‘The fact is that from the moment of his arrival he had kept the ape under lock and key, let nobody see it, all this was a clear indication that he was up to no good. Evidently, that damned beast had been prepared for its task long before and all he had to do was point it at the victim for it to carry out its task. This is how Kartzeff distanced himself from the crime, substituting a creature that had no sense of what it was doing, thus guaranteeing his own safety from punishment.
‘I fully comprehended his train of thought and action, but I have to admit that as an intelligent man he too read my mind and intuitively realized he could not escape from me. Of that he must actually have been convinced on the very first day we met, and when we arrived the very first time he immediately decided to put an end to us. You, of course, hadn’t noticed that we had been assigned a room in which the window had a pane with a broken latch, nor that the room in which old Kartzeff had been strangled had a pane with a similarly broken latch.
‘But on that occasion, his plan did not work. With foresight, I had nailed down the pane and for it to be opened there would have to be enough noise for us to be alerted. And that wasn’t part of the villain’s plan. I think you saw him in the window during our stroll last night—’
‘Oh, I shall never forget that look, a mixture of fear and loathing,’ I said.
‘If until then I had any reservations about his guilt, all doubt vanished from that moment. And so, during the night, I waited for confirmation of my presuppositions,’ said Holmes. ‘In any case, there’s not much more to tell you about the most recent events. You saw for yourself how an invisible hand tried to open the pane for that cursed animal to get into our room. Now, Watson, all that’s left is to lure him to a last desperate step. As soon as we return, I will announce that we have decided to depart for the city and, depending on how he reacts, we’ll decide what to do next. In the meantime, let us take our time getting back.’

We strolled back.
Boris Nikolayevitch was busy in the yard, handing out some sort of orders concerning household matters, when Sherlock Holmes approached and firmly stated that we had to return to Moscow this very day.
A hardly discernible gleam appeared in Kartzeff’s glance. But it was only momentary and, taking himself in hand, he said indifferently, ‘I am so sorry you cannot stay longer, but it can’t be helped. Work must come first. If you don’t intend to stop off at Silver Slopes, I’ll send you to the station by the direct road. I am only sorry that I cannot do so immediately. My horses are all out on the road and you’ll have to wait a few hours.’
‘Oh, that’s no problem,’ answered Sherlock Holmes.
‘I’ll give instructions for you to be driven to the ferry. It belongs to me, by the way. From there, the same horses will take you to the station.’
‘Excellent!’ said Sherlock Holmes.
We thanked him again and went inside, where we chatted with Nikolai Nikolayevitch and Boris Nikolayevitch who occasionally dropped in on us. Nevertheless, hour after hour went by and no horses appeared.
At a convenient moment, when both brothers were out of the room at the same time, Holmes whispered to me softly, ‘I forgot to tell you another little detail. This morning a sock went missing. I deliberately placed my boots outside the door and stuffed my socks inside them. Tell me, why do you think a sock went missing?’
‘I haven’t a clue. Now why should he need an old sock of yours,’ I said with a smile.
‘All the same, it is a serious matter,’ said Holmes. ‘I am nearly certain that he needed the sock for that ape to scent.’
Dinner was served at five and went off normally. It was another two hours before the host informed us the horses were ready and awaited us by the porch. But even here there was a delay. Kartzeff examined the carriage and claimed it hadn’t been properly oiled. He gave instructions for it to be oiled all over again. It was clearly a deliberate attempt to delay us further.
Night was beginning to fall when, at last, we thanked the brothers for their hospitality, bade them farewell and departed. After a mile along the road, the carriage entered a forest. Now the sun set and it became completely dark.
‘Be even more on your guard and hold on to your revolver,’ Holmes whispered.
As we drove into the forest, the driver slowed down.
