“I’ve made a ring round that room, anyhow,” he said. “They can’t all four of them be Mr. Welkin’s accomplices.”
Lucknow Mansions were, so to speak, on a lower platform of that hill of houses, of which Himylaya Mansions might be called the peak. Mr. Flambeau’s semi-official flat was on the ground floor, and presented in every way a marked contrast to the American machinery and cold hotel-like luxury of the flat of the Silent Service. Flambeau, who was a friend of Angus, received him in a rococo artistic den behind his office, of which the ornaments were sabres, harquebuses, Eastern curiosities, flasks of Italian wine, savage cooking-pots, a plumy Persian cat, and a small dusty-looking Roman Catholic priest, who looked particularly out of place.
“This is my friend Father Brown,” said Flambeau. “I’ve often wanted you to meet him. Splendid weather, this; a little cold for Southerners like me.”
“Yes, I think it will keep clear,” said Angus, sitting down on a violet-striped Eastern ottoman.
“No,” said the priest quietly, “it has begun to snow.”
And, indeed, as he spoke, the first few flakes, foreseen by the man of chestnuts, began to drift across the darkening windowpane.
“Well,” said Angus heavily. “I’m afraid I’ve come on business, and rather jumpy business at that. The fact is, Flambeau, within a stone’s throw of your house is a fellow who badly wants your help; he’s perpetually being haunted and threatened by an invisible enemy—a scoundrel whom nobody has even seen.” As Angus proceeded to tell the whole tale of Smythe and Welkin, beginning with Laura’s story, and going on with his own, the supernatural laugh at the corner of two empty streets, the strange distinct words spoken in an empty room, Flambeau grew more and more vividly concerned, and the little priest seemed to be left out of it, like a piece of furniture. When it came to the scribbled stamp-paper pasted on the window, Flambeau rose, seeming to fill the room with his huge shoulders.
“If you don’t mind,” he said, “I think you had better tell me the rest on the nearest road to this man’s house. It strikes me, somehow, that there is no time to be lost.”
“Delighted,” said Angus, rising also, “though he’s safe enough for the present, for I’ve set four men to watch the only hole to his burrow.”
They turned out into the street, the small priest trundling after them with the docility of a small dog. He merely said, in a cheerful way, like one making conversation, “How quick the snow gets thick on the ground.”
