And, doing so, he made a discovery. There was an angle at the corner of the house in which was a window set farther back. Standing on one spot, you counted this window as the first, and the first one built out over the Council Chamber as the second, but move a few yards to the right and the part built out over the Council Chamber appeared to be the end of the house. The first window was invisible, and the two windows of the rooms over the Council Chamber would have appeared the first and second from the end. Where exactly had he been standing when he had seen the light flash up?
Anthony found the question very hard to determine. A matter of a yard or so made all the difference. But one point was made abundantly clear. It was quite possible that he had been mistaken in describing the light as occurring in the second room from the end. It might equally well have been the third.
Now who occupied the third room? Anthony was determined to find that out as soon as possible. Fortune favoured him. In the hall Tredwell had just set the massive silver urn in its place on the tea tray. Nobody else was there.
“Hullo, Tredwell,” said Anthony. “I wanted to ask you something. Who has the third room from the end on the West side? Over the Council Chamber, I mean.”
Tredwell reflected for a minute or two.
“That would be the American gentleman's room, sir. Mr. Fish.”
“Oh, is it? Thank you.”
“Not at all, sir.”
Tredwell prepared to depart, then paused. The desire to be the first to impart news makes even pontifical butlers human.
“Perhaps you have heard, sir, of what occurred last night?”
“Not a word,” said Anthony. “What did occur last night?”
“An attempt at robbery, sir!”
“Not really? Was anything taken?”
“No, sir. The thieves were dismantling the suits of armour in the Council Chamber when they were surprised and forced to flee. Unfortunately they got clear away.”
“That’s very extraordinary,” said Anthony. “The Council Chamber again. Did they break in that way?”
“It is supposed, sir, that they forced the window.”
Satisfied with the interest his information had aroused
