A tiny rescue dog. A spoiled house cat. A big mystery to solve.

My crazy old Nan loves making decisions on a whim. Last week, she took up flamenco dancing. This week, she's adopted a trouble-making Chihuahua named Paisley. This wouldn't be much of a problem, were it not for the very crabby tabby who also lives with us.

Man, I never thought I'd miss hearing Octo-Cat's voice, but his silent protest is becoming too much to bear, especially since we just opened our new P.I. business together.

Things go from bad to worse, of course, when Nan and I discover that someone has been embezzling funds from the local animal shelter. If we can't find the culprit soon, the shelter may not be able to keep its lights on and those poor homeless pets won't have anywhere to go.

Okay, so I just need to find the thief, rescue the animals, and save the day—all while trying to find a way for Octo-Cat and Paisley to set aside their differences and work together as a team. Yeah, wish me luck...
