The Locked Room: Sjowall, Валё

The eighth book in the classic Martin Beck detective series from the 1960s and 70s – the novels that shaped the future of Scandinavian crime writing.
Hugely acclaimed, the Martin Beck series were the original Scandinavian crime novels and have inspired the writings of Stieg Larsson, Henning Mankell and Jo Nesbo.

In one part of town, a woman robs a bank. In another, a corpse is found shot through the heart in a room locked from within, with no firearm in sight. Although the two incidents appear unrelated, Detective Inspector Martin Beck believes otherwise, and solving the mystery acquires the utmost importance. Haunted by a near-fatal bullet wound and trying to recover from the break-up of his unhappy marriage, Beck throws himself into the case to escape from the prison that his own life has come to resemble.
