They reached Town at twelve—owing to Wimsey’s brisk work at the wheel—and went straight to Scotland Yard, dropping Bunter, at his own request, as he was anxious to return to the flat. They found the Chief Commissioner in rather a brusque mood—angry with the Banner and annoyed with Parker for having failed to muzzle Pillington.

“God knows where she will be found next. She’s probably got a disguise and a get-away all ready.”

“Probably gone already,” said Wimsey. “She could easily have left England on the Monday or Tuesday and nobody a penny the wiser. If the coast had seemed clear, she’d have come back and taken possession of her goods again. Now she’ll stay abroad. That’s all.”

“I’m very much afraid you’re right,” agreed Parker, gloomily.

“Meanwhile, what is Mrs. Forrest doing?”

“Behaving quite normally. She’s been carefully shadowed, of course, but not interfered with in any way. We’ve got three men out there now—one as a coster—one as a dear friend of the hall-porter’s who drops in every so often with racing tips, and an odd-job man doing a spot of work in the back-yard. They report that she has been in and out, shopping and so on, but mostly having her meals at home. No one has called. The men deputed to shadow her away from the flat have watched carefully to see if she speaks to anyone or slips money to anyone. We’re pretty sure the two haven’t met yet.”

“Excuse me, sir.” An officer put his head in at the door. “Here’s Lord Peter Wimsey’s man, sir, with an urgent message.”

Bunter entered, trimly correct in bearing, but with a glitter in his eye. He laid down two photographs on the table.

“Excuse me, my lord and gentlemen, but would you be so good as to cast your eyes on these two photographs?”

“Finger-prints?” said the chief, interrogatively.
