"The very man himself," he cried.

"Yes, Anstruther," Seymour said, in his deep, ringing voice. "Friend Anstruther. Shall we ask him in?"

[CHAPTER XXXVII.]

A PREGNANT MESSAGE.

There was no mistaking the fact that it was Anstruther who was standing outside and speaking in tones which denoted that he was not altogether pleased with himself. It might have been a coincidence, or, at the same time, it might have been intentional; though the latter suggestion did not appear probable.

"Surely he can't have found us out yet," Jack cried. "If he had done so it would hardly be policy to make so much noise about it. What do you think, Mr. Bates?"

Bates responded cautiously that he did not know what to think. The real solution came from Seymour.

"There is no coincidence about it at all," he said. "We know perfectly well that Anstruther is a clever criminal, but even clever criminals cannot bring off important campaigns without the aid of subordinates. I have not taken up my quarters here entirely by accident, though, of course, it was necessary for me to be as far off the beaten track as possible. I have seen Anstruther here on more than one occasion, and I think you will find he has come to consult one of his satellites."

"There must be a good few shady people here," Bates observed, "though I don't know much about the locality."

Seymour explained that there were plenty of doubtful characters living in the tenement. He suspected at least three burglars who had rooms on the same floor. Probably Anstruther was looking for one of these, and for some reason or other the fellow had denied himself. The loud tones had ceased now, and it was evident that Anstruther had either left the house or found the man of whom he was in search. The discovery, however, was too important to be allowed to rest like that, and Bates had a proposition to make. He suggested the advisability of putting one of his own spies on to watch Anstruther and keep an eye upon him for the rest of the day. There would not be the slightest uncertainty about this, seeing that Anstruther was so well known to the police generally.
