Later, at Scotland Yard, Angel interviewed the Commissioner.

“What sort of a man is Boyden to work with?” asked Mr. Commissioner.

“A most excellent chap—good-natured, obliging, and as zealous as the best of ’em,” said Angel, which was his way.

“I shall leave him in charge of the case,” said the Chief.

“You couldn’t do better,” said Angel decisively.

Then he went home to his flat in Jermyn Street to dress for dinner.

It was an immaculate Angel Esquire who pushed through the plate-glass, turn-table door of the Heinz, and, walking into the magnificent old rose dining-room, selected a table near a window looking out on to Piccadilly.

The other occupant of the table looked up and nodded.

“Hullo, Angel!” he said easily.

“Hullo, Jimmy!” greeted the unconventional detective.
