|Debut:||The Adventures of Sly Cooper: Volume 1|
|Occupation:||Detective for Interpol|
Carmelita's executive assistant, Winthorp also has a crush on her that is hard to miss. Unfortunately for Winthorp, Carmelita's preoccupation with her work prevents her from noticing his innocent affections. To top it off, the dweeby, out-of-shape Winthorp cannot possibly compete with the charming, athletic force that is Sly Cooper. He appears only in the comics. He is an otter.
- Winthorp never appeared in any of the games, but it was predicted that in the Monaco level he would have appeared, due to a strong police presence. Since the Monaco level never made it into the game, Winthorp remains a mystery.
