The Outcast Dead. The Dr Ruth Galloway Mysteries 6

Historical crimes involving a Victorian child killer may hold the key to several contemporary deaths in this macabre outing for Dr Ruth Galloway, forensic archaeologist. 'Told with a deepening sense of the unease, seasoned with a touch of the occult' Daily MailRuth has excavated a body from the grounds of Norwich Castle, which was once a prison. The body may be that of Victorian murderess Jemima Green.
Called Mother Hook for her claw-like hand, Jemima was hanged for the murder of five children. DCI Harry Nelson has no time for long-ago killers. Investigating the case of three infants found dead, one after the other, in their King's Lynn home, he's convinced that their mother is responsible. Then a child goes missing. Could the abduction be linked to the long-dead Mother Hook? Ruth is pulled into the case, and back towards Nelson.
