The Devil’s Workshop, Alex Grecian

Dangerous prisoners are on the loose in London, some with old scores to settle with members of the murder squad.

While Inspector Day’s officers are determined to recapture them, Day himself finds his investigations hampered by an old mentor who seeks a different kind of justice for the escapees.

And deep below London’s streets waits the unthinkable, one whose name caused a city wide panic, now freed to kill again.
