Volanie démonov(1968)

In Slovakia, they also created a pair of investigators who have appeared in several films. Volanie démonov is the third of them. The police officers, one Maigret-like, thoughtful, the other humorously hasty, this time solve a fire in a furniture factory and the deaths of two employees - one burned himself, the other fell into a dry well. The investigation of the complicated case takes a long time, but in the end it turns out that revenge can be extraordinarily strong and persistent.
