Wyllard's Weird begins with the death of a young foreign lady who falls from a train running
over a bridge through the Cornish countryside. Her identity is unknown and it is a mystery
weather this is an accident a suicide or a murder. Julian Wyllard a rich landowner tries to
clear matters up by employing a London detective but he only manages to diagnose a murder and
he directs suspicion on Wyllard's wife's favorite cousin Bothwell Grahame who will not
account for why he was on that train when the young woman was killed. Wyllard's wife in order
to clear her cousin's reputation asks the village coroner Edward Heathcote to make further
investigations into the case and he takes it upon himself to find the truth. Heathcote's
inquiries lead him to Paris and the mystery gets a new dimension when clues link the dead woman
with a cruel double murder which happened a decade ago.
