house as far as possible. This was not very far, for the second
story was closed off by a tall iron grating.

"Is the house door locked during the daytime?" asked Horn of the
servant.

"The front door is, but the side door into the garden is usually
open."

"Has it ever happened that any one got into the house from this
side door without your knowing it?"

"No, sir. The garden has a high wall around it. And there is extra
protection on the side toward the Promenade."

"But there's a little gate there?"

"Yes, sir."

"Is that usually closed?"

"We never use the key for that, sir. It has a trick lock that you
can't open unless you know how."

"You said you went to the theatre yesterday evening. Did your
master give you permission to go?"

"Yes, sir. It's about a year now that he gave me money for a
theatre ticket every Saturday evening. He was very kind."
