"I tell you, it gave me the creeps… Did this woman know you were going to arrest her?"

"Oh, I think she knows all right."

"Supposing she's committing suicide—"

The constable continued to strain his neck.

"Sounds as if I ought to look into it," he said. "But I don't care to leave my post. The inspector said I wasn't to move on any account. But if she's trying to escape justice—"

"She still hasn't moved," Simon said.

"No, she ain't moved."

"I don't see how going inside would be leaving your post," said the Saint thoughtfully. "You'd be just as much use as a guard outside the door of the flat as you are here."

"That's true," said the policeman.

He looked at the Saint.
