Toronto police detective Melissa Bonar lands an unusual homicide case in this enthralling mystery from Markman (Contra-Odessa). Edward Green was found in his apartment, half-naked, with his wrists slit, an apparent suicide. But there are several odd elements, including evidence that Green was sodomized before his death. He was found by his girlfriend before expiring from blood loss, but the only word he uttered that she understood was Wolverine. That clue leads Bonar to Brenda Rorke, an ex-con who was given the nickname of Wolverine in prison, for her fearlessness in confronting bigger female inmates bent on beating her up. After learning that Green once went by another name, the detective theorizes that he was assaulted in revenge for an unpunished crime that Rorke, who’s currently shacked up in a trailer park with a biker gang, may have been involved in. Markman toggles between past and present, leaving readers guessing on how everything will play out, and succeeds in making Rorke a character readers will sympathize with. Those interested in a nuanced look at what could lead someone to lash out violently will be satisfied. (Self-published)
