The new DI Hardcastle mystery set in June 1916. Hardcastle is sent to
investigate the murder of Colonel Sir Adrian Rivers, Bt. It seems the
baronet's second wife, much younger than Rivers, is neither distressed
by the murder, nor able to assist in the investigation. It is up to the
dogged Hardcastle, aided by DS Charles Marriott, to question an array of
characters and narrowly avoid being killed in a Zeppelin raid, before
the killer is eventually unmasked.
