Rocco and the Price of Lies — Adrian Magson

 
In this mystery set in 1960s France, a series of unusual suicides lead a rural police inspector to a troubling conspiracy.

Murder by suicide? Three senior government officials -- a judge, a politician, and an ex-police chief -- are all dead by their own hands.

Inspector Lucas Rocco finds himself once more working for the Interior Ministry: undertaking an investigation meant to avoid a government scandal and ignoring unpalatable truths. He's soon convinced that a common denominator must be at play . . .

Rocco uncovers top-level fraud, theft, and deception. And when he narrowly survives an attempt on his life, he realizes that he has nothing to lose by bringing the truth out in to the open, whatever the risks.
Perfect for fans of Stuart MacBride, Jean-Luc Bannalec, and Mark Billingham.
