Meet the Harlow Brothers.
Edward, a former college linebacker and ghost writer of a popular etiquette series, makes public appearances on behalf of the fictitious Aunt Civility as her nephew. His younger brother, Nicholas, is his secretary, personal assistant, and dogsbody.
When the brothers arrive at the isolated Inglenook Resort for a lecture on all things genteel, the discovery of a corpse in the guest room next door sends Edward’s ordered world spinning out of control.
With Edward in danger of losing his manners (and blowing his cover), Nicholas scrambles to keep the author's reputation unsullied and convinces him to team up to solve the crime. But soon the investigation turns into a sibling competition, and the price for losing is death.
