Join SPUD, the Super Perceptive Undercover Detectives, on their first fast-paced detective adventure.
Getting your first hearing aids can be nerve-wracking; especially when you have to wear them to school. When Callie realises her new hearing aids - 'the Slugs' - give her the unique ability to communicate with Bo the Mynah bird, some of her worries are lifted. In fact, having a pair of eyes in the sky might come in handy...
The duo team up with Callie's best friend, Grace, as they set out to catch a local thief who has been causing trouble all over town. Includes high-speed chases, a very peckish bird and purple POO!
