DCI Isaac Cook and his team are after a woman who is stalking London, killing men, and carving a number in each victim’s chest. They know the identity of the killer, but are unable to ascertain her motive, or find her. Cook is on the hot seat, at odds with a new commissioner at the Met, who is after him as much as the killer.
Murder is only a Number by Phillip Strang is the third book in the DCI Cook thriller series. The author takes the reader step-by-bloody-step through a chilling tale of murder and revenge, with a background of bureaucratic intrigue, that will keep you flipping pages until the end.
This is a bit more disturbing than the first two books in the series, but it provides more background on the main protagonist, as it explores his struggles with balancing his professional and personal lives. The antagonist is chillingly portrayed, but with a measure of empathy that makes her supremely real—and, all the more frightening.
I give this one four stars.
