Thirty years before Henning Mankell began plying his trade as writer of Scandinavian crime fiction, there was the husband-and-wife pair of Maj Sjöwall and Per Wahlöö. They collaborated on a series of ten police procedural novels starring Martin Beck, a superintendent with the Stockholm police. The Man on the Balcony is the third book.
Unfortunately, these books are somewhat difficult to lay hands on, but suffice it to say, if you spot them anywhere, grab them. For this is the original Scandinavian crime fiction, and what’s more, they are great stories as well.
