Spring has arrived in Glasgow and Leger has a new mystery to solve! When his neighbours return from their winter break in Spain, they begin fighting with the other residents on a daily basis and losing friends at every turn. Someone deliberately sets their garden shed on fire, endangering all humans and animals in the nearby homes. Leger then learns that his hedgehog friend was hibernating in the shed has suddenly vanished and he knows he must track down the arsonist. It won't be easy but this time he has the help of not one but two mollies. Ginger's daughter Amber has finally come of age and he deems her mature enough to help with his enquiries, but suddenly she seems reluctant to become involved and at times even hinders the investigation. Leger is determined to solve this case with or without Amber's help and track down the arsonist.
