She was halfway through her breakfast when the telephone bell rang, and she rose from the table and crossed to the wall. At the first word from the caller she recognized him.

"Why, uncle!" she said. "Whatever are you doing in town?"

The voice of John Minute bellowed through the receiver:

"I've an important engagement. Will you lunch with me at one-thirty at the Savoy?"

He scarcely waited for her to accept the invitation before he hung up his receiver.

The commissioner of police replaced the book which he had taken from the shelf at the side of his desk, swung round in his chair, and smiled quizzically at the perturbed and irascible visitor.

The man who sat at the other side of the desk might have been fifty-five. He was of middle height, and was dressed in a somewhat violent check suit, the fit of which advertised the skill of the great tailor who had ably fashioned so fine a creation from so unlovely a pattern.

He wore a low collar which would have displayed a massive neck but for the fact that a glaring purple cravat and a diamond as big as a hazelnut directed the observer's attention elsewhere. The face was an unusual one. Strong to a point of coarseness, the bulbous nose, the thick, irregular lips, the massive chin all spoke of the hard life which John Minute had spent. His eyes were blue and cold, his hair a thick and unruly mop of gray. At a distance he conveyed a curious illusion of refinement. Nearer at hand, his pink face repelled one by its crudities. He reminded the commissioner of a piece of scene painting that pleased from the gallery and disappointed from the boxes.

"You see, Mr. Minute," said Sir George suavely, "we are rather limited in our opportunities and in our powers. Personally, I should be most happy to help you, not only because it is my business to help everybody, but because you were so kind to my boy in South Africa; the letters of introduction you gave to him were most helpful."
