The Kribbirk Method

In the 1950s and 1960s, Detective Chief Inspector Robert “Bob” Kribbirk was one of Bellowsford’s most relied-upon investigators. His speciality was the pursuit: reconstructing where a person had been, and where they were going, from fragmentary sightings across the town.

Kribbirk insisted that a suspect’s journey should always be worked in both directions.

“Work it forwards. Then work it backwards. If both journeys lead to the same place, you’re probably getting close.”

The principle became part of Bellowsford police folklore. Detectives began shortening the whole method to two words: “Kribbirk it.”

When Bellowsford later developed its surveillance and pursuit-analysis system, there was only one name it could carry. Today, KRIBBIRK is a daily pursuit puzzle: one sighting, one route, one convergence point — every day. Players work a suspect’s route forwards from the starting point and backwards from each candidate destination, exactly as Bob Kribbirk taught.
