Martinsson, a character in Henning Mankell's "The Dogs of Riga," contrasts sharply with Svedberg. Approaching 30 years old and hailing from Trollhättan, Martinsson had long aspired to a career in law enforcement. His background shaped his approach to policing, making him somewhat impulsive and occasionally reckless.

Despite these flaws, Martinsson possessed a creative mindset, often generating good ideas. His ambition drove him to work persistently, especially when he believed he could resolve an issue. This determination and innovative spirit are central to his character in the narrative.
