Keeper of the Keys
Janny Wurts
 Once again, the setting of the novel is rural California, where Chan has been invited as a houseguest. He meets a world-famous soprano, Ellen Landini, who is murdered not too long after the meeting. Chan does not have far to look for suspects—the host is her ex-husband, as are three of the other house guests. Her servants, entourage and husbands all come under suspicion. Once again, Chan is expected to solve the murder, which he does by understanding the key clues—the actions of a little dog named Trouble, two scarves, and two little boxes. When he understands how the murder is committed, he learns the role of elderly house servant Ah Sing—the keeper of the keys.
