Tommy Frayne, President of the PIC for the next mystery, sees an ad in the newspaper offering a reward if someone finds a missing dog. The PIC decides to take on this challenge, using the cover story that they are looking for business for Dick's Lawn Service. They are wildly successful in getting lawn mowing business, but have no success in finding the missing collie. They have to expand the club to 25 members, auction off items their customers don't need, and, somehow, find the hidden hound. They get into trouble when some officials do what Bobby calls a "Bee Sting" trick on them. Luckily, their police officer club member, Tanya Patel, comes to their rescue.
