When you watch this movie, you will immediately notice that it does not follow the standard "Columbo" formula in which you know who the murderer is right from the start. Instead, we get a genuine mystery. That's because this movie is based on Ed McBain's novel "Jigsaw", originally published in 1970. This was one of his 87th Precinct mysteries, which did not originally feature Columbo.
Columbo is substituted for several different characters from the book, alternating from scene-to-scene. Sometimes he's the book's Detective Carella, other times he takes over for Detective Brown, who also appears in the movie. As confusing as this may sound, the movie is actually a very faithful adaptation of the book - even the pieces of the photo are identical to the illustrations in the book.
BTW, this isn't the only recent Columbo movie to be based on an Ed McBain novel -- "Columbo: No Time To Die" is an adaptation of the novel "So Long As You Both Shall Live".
