The Man Who Went Up in Smoke (original title: Mannen som gick upp i rök) is a mystery novel by Swedish writers Maj Sjöwall and Per Wahlöö, published in 1966.

In the novel, Beck returns to work and travels to Hungary to search for a missing journalist called Alf Matsson.

He was commissioned by a Swedish newspaper to fly to Budapest to conduct an interview with a boxer and report on political events.

The Stockholm police is tasked with finding the missing reporter, and send Martin Beck, who sacrifices his vacation to go to Budapest.

Beck and Kollberg have their first, short run-in with detective Backlund of the Malmö police force, who lacks the imagination required for his line of work, for which he thinks bureaucracy is a replacement.
