Dark Music (Rekke & Vargas #1) by David Lagercrantz

A murder investigation brings together two unlikely allies in a race to uncover a shadowy international conspiracy.

Professor Hans Rekke: born into a wealthy Stockholm family, world authority on interrogation techniques, capable of vertiginous feats of logic and observation. But he might just fall apart when the going gets tough, in a downward spiral of substance abuse and despair.

Micaela Vargas: community police officer, born to Chilean political refugees in a tough suburb, with two brothers on the shady side of the law, and a resilience none of her colleagues can match.

Vargas feels she has something to prove. She's tenacious and uncompromising, but she needs Rekke's unique mind to help her solve the case. Rekke has it all -- wealth, reputation -- but also a tendency to throw it all away. He needs Vargas to get him back on an even keel so he can focus his mind on finding the killer before they're both silenced for good.
