Jackdaw

Daughter of a notorious murderer herself, Detective Scarlett Delaney hasn’t been on the force for long when she finds herself heading up a mystifying new case. With three seemingly impossible murders to date, leaving each of the victims with calling-card scratches, the killer known only as “Jackdaw” feels untouchable... uncatchable, always claiming a shiny keepsake before disappearing into thin air.
That is until Scarlett encounters Henry Devlin, a charismatic but dangerous criminal with his own reasons for pursuing the Jackdaw. Together, they form an uneasy alliance, but as they get closer to their prey, the threat surrounding Scarlett intensifies – from the growing suspicions of her partner on the force, Henry's ruthlessly efficient employers... and, most terrifyingly, from the very monster that she is so desperately chasing...
An ambitious detective. A charming assassin... and their hunt for a serial killer. If you loved Thirteen by Steve Cavanagh, The Chain by Adrian McKinty or anything by Jennifer Hillier you will race through Jackdaw.
