Detective Ulf Varg is a man of refined tastes and quite familiar with the art scene in Malmö. So when art historian Anders Kindgren visits the Department of Sensitive Crimes to report a series of bizarre acts that have been committed against him, Ulf and his team swing into action. Fish stuffed into the vents of Kindgren's car and a manipulated footnote in a recent publication would be cause enough for an investigation, but when a painting Kindgren had confidently appraised as genuine is later declared to be a fake, it's clear that someone is out to tarnish his reputation.

Meanwhile, Ulf is also weathering personal issues, which quickly spiral out of control. When his lip-reading dog, Martin, engages in a contretemps with a squirrel that results in a grievous wound, Ulf must rush Martin to the veterinarian and weigh the merits of cosmetic surgery for animals. And later, when Martin's blood is found in the back of Ulf's classic Saab, Ulf finds himself the subject of a departmental investigation.

In the end, Ulf will have to muster all his detective skills and bureaucratic cunning to restore Kindgren's reputation--as well as his own.
