1929. The book begins: The girl was tempted by the open door. It was unusual for Hazzard to leave his door open. His habit was to shut it quietly and carefully, for like many other doors in Roper's Row it had seen better days, and was suffering from decrepitude, strained hinges and a stammering lock. Hazzard knew the habits of that door. Unless you were firm with it and made sure that the catch had caught, the door would swing slowly back into the room, uttering a little creaking moan. It was a faithless, treasonable door. It was ready to betray you and your secrets, and Hazzard had many reasons for wishing to keep the door closed.
