The Case of Careless Aliens

Sinister aliens are on the loose ... Money is appearing mysteriously in unexpected places around the city. UFOs have been spotted in the sky. If aliens are trying to take over, they have been very careless indeed! Will the Superlative Supersleuths be able to foil their diabolical experiments, or will everyone end up being mind-controlled? Case Notes: Vipul's anti-alien foil hat isn't effective. He's also very annoying. Have the aliens made a deal with the tooth fairy? Why is Ashwin obsessed with poop pancakes?
