An English colonel is found dead in his bathtub—hours before he intends to confess.

The marks on his arms suggest murder. A crucial page is missing from his statement. And everyone inside his secluded coastal home has something to lose.

A wife who knew.

A daughter summoned from England.

A lawyer who wanted him silenced.

And a mother whose son died ten years ago in an accident that may not have been an accident at all.

Commissioner Lucien must uncover what Edward Harcourt was about to reveal—and who killed him to keep it buried.
