Going to the Dogs — Dan Kavanagh

Duffy receives a message from the country mansion of Vic Crowther, an old and dubious acquaintance, that a dead body has been found in his library. So the uncommon street-smart, cynical, neurotic, bisexual private investigator leaves London and proceeds to what should be a classic, genteel rural estate only to discover that the murder victim is Crowther's dog. This weekend guests are as ill-suited to the setting of Braunscombe Hall as is Duffy, who, when his stay is prolonged, finds himself with an epidemic of crime on his hands and a houseful of suspects who don't always take to his presence. Even their legal behavior isn't very nice. And Duffy worries that British society is going to the dogs.
