There's been a great upset in the barn tonight. While everyone was asleep, someone has come in and, it is alleged, stolen the cow's spots! A new case for Roger the Mouse, the most daring detective whom nobody has yet outwitted. He's been known as Roger since the day his mother decided that this was the name that best suited his face, and in particular his ears, but has more commonly been known as Roger the Mouse Detective since he solved the case of the mysterious theft of Rogelio the Parrot's voice. After solving that case he thought it would be best to turn professional and he underwent training at the Rodent Detective Academy in Southampton. Since then he has solved several cases, including such high profile incidents as the theft of the diamond necklace belonging to the Queen of England's favourite pet, a strange case which he might tell us about one day...
