Mai Cheval and Per Vale are Swedish journalists, authors of the famous series of novels about Commissioner Martin Beck, which received prestigious literary awards in both Europe and America. In a new series of investigations, Martin Beck and his colleagues are faced with murders that, judging by the identities of the victims, seem logical and even natural. But knowing the motives for crimes does not bring the police any closer to solving them. Only the special quality of Commissioner Beck, which he himself calls “police intuition,” allows him to pull the right strings and unravel the whole tangle. This book includes three novels from the decalogy: A Man Called What's-His-Name (1969), Police, Police, Mashed Potatoes! (1970), based on which a film called “Unfinished Dinner” was shot at the Riga Film Studio in 1979, and “The Scoundrel from Säflö” (1971).
