Petey is a female bounty hunter who’s perplexed by a mysterious bounty that was posted: the culprit is a fellow named Blue Cheese, but his bounty is -$100 – essentially there’s a fine for turning him in! Confused as to what this means, Petey chats with the seventeen-year-old bartender and mystery solver Suna to figure out what’s going on. Will she take up the strange bounty and figure out why it exists?
Both "$100 is Too Cheap" and "The Teddy Bear Murder Case" (one of the chapters in Le Theatre de B) are one shots about detectives solving a case. The setting and art are different, but both detectives take steps, with some help, to solve the case. If you liked a little mystery and one shots, check these out.
