For Sam and Sabrina a stay at Grandma's house turns out to be a roller coaster adventure when the eccentric Professor Molecule comes to call with his FantastIc Listening Machine. Voices from the past tell of pirates, hidden treasure, and secret hiding places. A fun filled journey which takes the children and their sleepy old dog Marcus into the world of Jack Hedgeman and many exciting discoveries. The Professor's machine astounds the children, drawing out conversations from hundreds of years ago, and sends them, from the genteel surroundings of Grandma's old house, hurtling down into the damp cold darkness of a long forgotten cavern.
A great first chapter book for the independent reader, suitable for both boys and girls aged 8-12 years.
