"Please convey our thanks to Mr. Hilton. I'm sure we shall enjoy the wine."

When Tomlinson and Harris had gone, the eyes of the two detectives met. They said nothing at first, and it may be remembered that they were reputedly most dangerous to a pursued criminal when working together silently. Winter took the decanter, poured out a small quantity into two glasses, and gave Furneaux one. Then they smelled, and tasted, and examined the wine critically. The rich red liquid might have been a poisonous decoction for the care they devoted to its analysis.

Furneaux began.

"I have so many sleepless nights that I recognize bromide, no matter how it is disguised," he murmured.

"Comparatively harmless, though a strong dose," said Winter.

"If one has to swallow twenty grains or so of potassium bromide I can not conceive any pleasanter way of taking them than mixed with a sound port."

Winter filled one of the glasses four times, pouring each amount into a tumbler. Furneaux looked into a cupboard, and found an empty beer bottle, which he rinsed with water. Meanwhile Winter was fashioning a funnel out of a torn envelope, and in a few seconds the tumblerful of wine was in the bottle, and the bottle in Winter's pocket. This done, the big man lit a cigar and the little one sniffed the smoke, which was his peculiar way of enjoying the weed.

"It was most thoughtful of Mr. Hilton Fenley to try and secure us a long night's uninterrupted sleep," said Winter between puffs.

"But what a vitiated taste in wine he must attribute to Scotland Yard," said Furneaux bitterly.
