That was a ‘smart’ stroke of business, which delighted Coutts almost as much as the prospect of gaining such a large sum of money, and of making the ‘old fellow’ stump up in spite of himself. There was, too, in his mind a kind of moral fitness in the transaction; for it would be paying out this precious uncle for some of the annoyance he had caused his father. In addition, there was to be reckoned the satisfaction of outwitting one of the cutest scamps he had come across—a fellow who had overreached even him—for with the same move which was to checkmate Shield, Wrentham would be paid out too. He gave little consideration to his brother, having no doubt that he would escape all right somehow.

He had secured the services of a detective who possessed the highest qualifications for his office, namely, he was not like a detective at all in manner, appearance or speech. Meeting Sergeant Dier in an ordinary way, you would regard him as a successful commercial man. There was not the slightest flavour of Scotland Yard about him. He was a good actor, a good singer, and a capital story-teller. Some of his most important discoveries were made whilst he was entertaining a roomful of company with his merry anecdotes. The secret of his success lay partly in a natural gift for his business, his enthusiasm, and the good-nature which underlay it all. He never allowed a scoundrel to escape; but he dealt very gently with any poor creature who might be betrayed into a first crime.

When Coutts reached his office, Sergeant Dier was waiting for him. Any one looking at the detective as he stood, bareheaded, reading a newspaper, would have imagined that he was one of the bank officials. He accompanied Coutts to his private room.

‘Well, what news have you?’

‘Our man has everything prepared for a holiday abroad,’ was Dier’s smiling reply.

‘Can he get away?’

‘O dear, no; he is at present under the eye of one of my friends, and he has been obliged to delay his departure until to-morrow, owing to a difficulty he has found in collecting his funds on such short notice.’

‘Is that all?’

‘There is a little more,’ said Dier complacently. ‘I have found a man who can identify his writing under any disguise.’

‘Who is he?’
