Welcome to Oldminster, a quaint little town where there's always a mystery to be solved.
Frank Renfield, Baron of Renfield Hall, will stop at nothing to save himself from ruin. Even if that means marrying his daughter off to a rich American. Unfortunately for him, she is already in love with a penniless nobody named Alan Lavender—to the glee of Alan's greedy uncle Guy. He's been nosing into the Renfields's murky past, and he says he's uncovered a secret. Something so shocking it casts a shadow over Frank's entire legacy.
Tensions run high at the hall, until Guy Lavender turns up dead. A convenient coincidence for Frank? Detectives French and Edwards are on the case. But in a town full of secrets, the truth can be hard to find. And Guy's won't be the only body to fall before their work is done ... Who will be next to die under the Renfields's roof?
