"What do you want here?" he called out without turning round.

"Good evening, Aspeland," said Wallion, "how are you?"

Aspeland turned quickly.

"'The Problem Solver,' as sure as I am alive," he said awkwardly, "however did you get here? Are you a conjurer? Has the news of this tragedy already reached the town?"

"No, not the town, but it has reached me; it is something in my line of business you see. Have you got him fast?"

"Him? Who?"

"Why, the murderer, of course."

"Well it isn't a HE, it's a SHE," Aspeland answered, "and she is here in this house, and we are going to be after her."

"How do you know she is here in this house?"

"Because she was seen running out of the studio after the crime, also because nobody saw her go down the stairs, though heaps of people were about. I tell you she is in hiding somewhere not far off, and if I have to send fifty men after her I mean to catch her."
