Alchemist's Son

When Pip and Tim move into an old manor house, they hear strange tapping noises at night that seem to be coming from behind the wall. They tap back, a hidden panel opens - and out comes Sebastian, a boy dressed in bizarre, old-fashioned clothes and claiming to have come from the 15th century!

Sebastian, the alchemist's son, must face a new evil. An old enemy, a magician whose power lies in stealing souls, has reappeared in a new and cunning disguise. He is using an ancient spell book to bring about a terror beyond imagining. Once again, Pip and Tim brave sorcery and danger to help Sebastian as he pursues his enemies through the centuries.
