Books with title Jay-Pea-Eyes Aka Junior Private Investigators

Three children go missing and police organise a massive search of the town of Dudleigh and surrounding areas. A call from a security officer at Russington Hospital immediately has several Detectives heading for the Accident & Emergency Department. All three missing children have somehow been returned to the Hospital. No-one sees or hears anything; it's as though the children appeared out of the sky. The Doctor is puzzled - the children are in excellent health but are refusing to talk to anyone, not even their own parents. Local detectives are baffled. Where have they been? What have they been doing? Why won't they talk? All questions the police want answered. And urgently. When another young girl goes missing her 10 year old brother Harry and his three friends, Stan and identical twins Polly and Lily, are determined to find her and solve the mystery once and for all. Will they solve the mystery before the Police? Can they find out the 'Where's and the What's' and also the 'Why's and the How's?'

It's school holiday time and the JPIs are staying at their favourite place in Portsmouth, UK.The Pelican Hotel is owned by Stan's gran Muriel Larkin and she's always delighted to see them arrive. This holiday is different. A horrible black depression hovers over the hotel. The children sense it straight away but their parents won't discuss it. Stan won't talk, not even to Harry his best friend and locks himself in his bedroom. The JPIs are warned not to step foot on Muriel's private beach because the sand has turned green and the council think it's poisonous. That meant they couldn't go near Sea Shell Cave either. Earth tremors at night are so ferocious they rock the very foundations of the building. Muriel thinks everything is cursed; the beach, the hotel and Sea Shell Cave.The JPIs don't have the same feeling. After noticing strange goings on in the hotel and on the public beach, they think something or someone is responsible for everything that is happening. They intend to find out who and why. It will lead them into life-threatening danger and will be their toughest case yet.
