"Beau" (John Hamilton) and "Chattie" (Vivien Oakland) invite a rather eclectic mix of folks to join them for a party at their remote island home. Or do they? The arrival of their guests proves quite bemusing as they didn't actually ask anyone! Who has lured these people here and why? Well body number one arrives shortly afterwards (then disappears) and as others soon start to mount up, we have a mystery that it falls to mechanic "Blair" (Peter Cookson) and the suspicious "Ann" (Lorna Gray) to try and solve before they, too, go the way of the dodo at the hands of the famed ghost of this ramshackle pile. It's not very often we see a geiger counter feature in a murder mystery, but armed with it's glowing light and a bit of light-heartedness, we race through an hour amiably. Nobody will take any acting or writing plaudits from this, but as a standard Saturday afternoon feature, it does fine and probably have inspired countless editions of "Scooby Do"!
