"So far, so good," he said. "Are they going to send round the motor car? I shall be very glad to see our elderly clerical friend here."

The officer indicated that everything would be done in accordance with Field's desire.

"There was one other man I wanted," he said. "Not that one ever gets everything in cases like this. Unless I am greatly mistaken, there was another man in Edward Street, a tall man——"

"Called the doctor," the officer said eagerly. "I know all about him, because they told me over the wire from Southwark exactly how the raid was made. The housekeeper called to some 'doctor,' but the police couldn't find him. I expect he found some way of getting off."

"He'll come here," Field said emphatically. "He'll come if only to tell his pals exactly what has happened. He'll come post haste in a cab. If he does I shall bag the lot. This is going to be a fine evening's work."

Seeing that nothing further was expected of him, the officer saluted and went beyond the gate. Still there was no sign from the house, and the silence and suspense were growing intolerable. Mark ventured to suggest that something should be done.

Field turned upon him with the fury of a tiger. By his anger he showed that he, too, was feeling the strain of suspense.

"Confound you, sir," he said, "allow me to know my business best. Here I am close to the solution of

one of the strangest and most daring crimes of the century, and yet you are asking me to spoil it by the raw haste of a schoolboy."

"Perhaps I had better go," Mark said. "Come with me, Miss Sartoris. Let us leave together. It will be better for you that way."
