So, is this timeline correct?
1. Landon steals the artwork (and commits a murder in the process)
2. Landon brings the stolen artwork somewhere
3. Frank touches the artwork, leaving fingerprints
4. Landon moves the artwork further to Elaine's place, where it is inaccessible to Frank
5. The artwork is discovered at Elaine's place, and Landon accuses Elaine of the theft
6. Frank argues that the artwork couldn't have been at Elaine's place all the time, because of Frank's Fingerprints
7. Landon accuses Frank of having left the fingerprints just now
8. But Frank is wearing gloves so the fingerprints must be older
Yes! Yes yes, 100% yes! Thank you for finally killing this one off!
To LemonCurry's perfect solve above, I'll add some extraneous details--
This is from a Columbo episode (not the one I took the title from, that would be too easy). Of course, Frank is Columbo.
At an earlier point in the episode, the murderer, an art dealer, allows the detective to hold the stolen artwork, but it is wrapped in paper, so Columbo does not recognize it as evidence. Later "Landon" causes the police to find the planted artwork in the house of his mother, who was also a suspect. Columbo threatens to fingerprint the wrapping paper, suspecting that he will find his own prints and therefore prove the that the stolen art was in Landon's possession earlier. Landon insists to the other detectives that Columbo is framing him, that he just touched the paintings while they weren't looking. Columbo, smug as ever, pulls his hands out of his pockets to reveal he has been wearing gloves the whole time.
