Poor Gareth had no idea what he was going to find, least of all that a raving lunatic murderer would be on the loose exactly on the location he had been summoned to. Proof, her note had said. He thought she had found a witness in the brothel, or perhaps there was a body. He had no idea what awaited him.

At least he had had the presence of mind to slip a gun under his coat.

He found the address and looked up at the front entrance. The door was closed. Did he knock or did he slip in?
