The Killings at Kingfisher Hill

The Killings at Kingfisher Hill by Sophie Hannah Hercule
Poirot is traveling by luxury passenger coach from London
to the exclusive Kingfisher Hill estate. Richard Devonport
has summoned the renowned detective to prove that his
fianc?e Helen is innocent of the murder of his brother
Frank. Poirot will have only days to investigate before
Helen is hanged but there is one strange condition
attached: he must conceal his true reason for being there
from the rest of the Devonport family. The coach is forced
to stop when a distressed woman demands to get off
insisting that if she stays in her seat she will be
murdered. Although the rest of the journey passes without
anyone being harmed Poirot’s curiosity is aroused and his
fears are later confirmed when a body is discovered with a
macabre note attached . . . Could this new murder and the
peculiar incident on the coach be clues to solving the
mystery of who killed Frank Devonport? And if Helen is
innocent can Poirot find the true culprit in time to save
her from the gallows?
