“We may have to go farther,” Reggie said, and Gordon laughed.

“Are you in this, sir?” The Inspector turned on him.

“Professional secret, dear boy.”

Reggie led the way to the station dining-room. “I don’t know the cook. But let’s hope for the best. A tirin’ day, an active evening. Strength is what we need. Strength without somnolence. Salmon, I see. Lamb chops, I would add. One of your younger ducks would comfort me. Do you sleep after Burgundy, Inspector? A warm night, as you say. Larose is a genial claret. Let us all be genial.”

“Well, you’re a bit supercilious,” the Inspector complained.

“How can you say so? I am keeping all the glory for you. Glory on ice. All ready for Inspector Mordan. So gather you roses while you may. Talking of roses, what do you think of the hybrid Austrian briers?” He explained what he thought of them to a silent audience, sliding gracefully into an appreciation of salmon eaten at Waterford, at Exeter, and at Berwick. Few are the men who will not talk about food. The detectives produced much valuable experience of bourgeois cookery, and the dinner went merrily. In its later stages Reggie became silent and watched the clock. He seemed to grudge Inspector Mordan his cheese, and as soon as it was swallowed made a move.

“Well, doctor, I did think we should have had some coffee,” the Inspector chuckled.

But Reggie was already making for the door. By the door stood his chauffeur looking for him. Reggie beckoned impatiently to the detectives and followed the chauffeur out. He led them to the main line departure platforms. It was near the time of the Harwich boat-train. A dark, wiry man was registering some luggage for Amsterdam. By his side stood a veiled woman of full figure. Both he and she carried suit-cases. As the man turned round he bumped into Reggie, who was looking the other way, and seemed to have some difficulty in disentangling himself. He glared at Reggie and hurried away. The woman was ahead of him.

Reggie grabbed Superintendent Bell. “See that pair. Take them both. Picking my pocket. Get the bags.”

Bell and Mordan hurried after the pair. Bell tapped the man’s shoulder, and he jumped round.
