I recently discovered an editing error in "A Stitch in Crime." When Dr. Mayfield goes to Harry Alexander's apartment, the mailbox shows Alexander lives in Apt. 10. However, when Alexander comes in before being drugged and subsequently leaves afterward, he enters and exits through a door with the number 25 on it. Check it out!

good catch. very similar to the goof in "murder by the book" with the parking space number. you have good eyes!

Good catch Josh. Now, let's sue Univeral over this and get them to include a Peter Falk interview in season six!
