Come Home to Danger — Estelle Thompson

Charles Waring has come home to Queensland to attend his mother's funeral and several other people inadvertently overhear his remark, intended only for a family friend to hear. The chain of events which follows convinces Charles that his mother was murdered because she knew a terrible secret from someone's past, and he finds himself in a deadly game of cat-and-mouse as he tries to unravel the mystery. Meanwhile, he must face the certainty that someone among those he has come to care about poses a cruel threat.
