The Frogs Band and the Mystery of Lion Castle

On his way to an International Conference of Sleuths in his hot air balloon, Alphonse le Flic, eminent detective, is forced to land in the courtyard of Lion Castle when his balloon suffers a puncture.

Also seeking help from the castle’s affable owner is the famous Frog Band, whose truck has broken down. Through the innocent curiosity of the band’s tuba player, Shortie Frog, a chain of events is set in motion that results in the solving of an age-old mystery: what became of Brooker’s ancestor, Clarence de Lyon?
