‘He had a large tin box,’ proceeded Tauchnitz, in explanation, ‘in his own room, in which he kept documents which did not relate to the business.’

‘You don’t know what was in that box, I suppose?’

‘I haven’t the remotest idea.’

‘Could I have access to the box, do you think?’

‘No; I am sure you could not. I have sent it away to his family.’

The opinion expressed by Mr. Tauchnitz of his partner’s probity and honour was but a reflex of that which was held throughout the town—indeed, it is not too much to say throughout the greater part of Russia; for Ferguson belonged to that class of men who understand the art of getting themselves talked about. He had been wonderfully successful as a merchant, and his name was associated with so many public acts, and he had shown so much public spirit, so much enterprise, and had advocated so many measures calculated to benefit the working classes, that he had come to be regarded as a benefactor, a philanthropist.

It is interesting to dwell upon these points, because the sequel will be in the nature of a surprise. Danevitch’s next step was to seek an interview with Donald, Mr. Ferguson’s eldest son, who was also a partner in the business—as, in fact, all the sons were. Danevitch displayed great caution in dealing with Donald. His experience with Tauchnitz impressed him with the necessity of exercising all the diplomacy he was capable of exercising. Donald was much distressed by his father’s sad end, and expressed a desire that no stone should be left unturned to bring his murderer to justice; but he evidently inherited his father’s reticence, and displayed in a very marked manner the Scotch characteristic of so-called caution.

‘Can you make any suggestion as to the motive for the murder?’ asked Danevitch.

‘It isn’t for me to do that,’ was the answer.

‘We know that it wasn’t robbery,’ Danevitch said.
