When the clocks strike, murder follows.
England, 1925. At a lavish country house party, a practical joke appears to have gone horribly, murderously wrong. It will be up to the unlikeliest of sleuths—the fizzingly inquisitive Lady Eileen 'Bundle' Brent—to unravel a chilling plot that will change her life, cracking wide open the country house mystery.
