“Ha!” said Anthony. “I smell a rat.”

“I wish I could smell some lunch,” said Bundle. “Do I ask the Scotland Yard man to have lunch with us, Mr. Cade? You’re a man of the world, you know about the etiquette of such things. We’ve never had a murder in the house before. Exciting, isn’t it? I’m sorry your character was so completely cleared this morning. I’ve always wanted to meet a murderer and see for myself if they’re as genial and charming as the Sunday papers always say they are. God! what’s that?”

“What” seemed to be a taxi approaching the house. Its two occupants were a tall man with a bald head and a black beard, and a smaller and younger man with a black moustache. Anthony recognized the former, and guessed that it was he—rather than the vehicle which contained him—that had wrung the exclamation of astonishment from his companion’s lips.

“Unless I much mistake,” he remarked, “that is my old friend, Baron Lollipop.”

“Baron what?”

“I call him Lollipop for convenience. The pronouncing of his own name tends to harden the arteries.”

“It nearly wrecked the telephone this morning,” remarked Bundle. “So that’s the Baron, is it? I foresee he’ll be turned on to me this afternoon—and I’ve had Isaacstein all the morning. Let George do his own dirty work, say I, and to hell with politics. Excuse me leaving you, Mr. Cade, but I must stand by poor old Father.”

Bundle retreated rapidly to the house.

Anthony stood looking after her for a minute or two and thoughtfully lighted a cigarette. As he did so, his ear was caught by a stealthy sound quite near him. He was standing by the boat-house, and the sound seemed to come from just round the corner. The mental picture conveyed to him was that of a man vainly trying to stifle a sudden sneeze.

“Now I wonder—I very much wonder who’s behind the boat-house,” said Anthony to himself. “We’d better see, I think.”
