Death Can't Take a Joke (Kiszka & Kershaw, Book 2) by Anya Lipska
The second Kiszka and Kershaw crime thriller.
When masked men brutally stab one of his closest friends to death, Janusz Kiszka - fixer to East London's Poles - must dig deep into London's criminal underbelly to track down the killers and deliver justice.
Shadowing a beautiful Ukrainian girl he believes could solve the mystery, Kiszka soon finds himself skating dangerously close to her ruthless `businessman' boyfriend. Meanwhile, his old nemesis, rookie police detective Natalie Kershaw is struggling to identify a mystery suicide, a Pole who jumped off the top of Canary Wharf Tower. But all is not what it seems...
Sparks fly as Kiszka and Kershaw's paths cross for a second time, but they must call a truce when their separate investigations call for a journey to Poland's wintry eastern borders...
