Plot

Cutter and his team are called in to locate a giant marine reptile that ate a lifeguard at a swimming pool. When the remains of a special forces diver are sent back through the anomaly, Cutter suspects his wife Helen is on the other side.

A prehistoric aquatic creature like a huge crocodile appears in a London swimming pool, eats a life guard, then vanishes. Later a special forces diver vanishes, but then the diver's bones turn up in a flooded basement in a town some way to the south west. Nick Cutter predicts that incidents will occur at places on a straight line through these two locations on the map of southern England. Eventually Cutter is allowed to go through an underwater anomaly, tethered by a safety rope a mile long. Finally, amid a prehistoric landscape, he meets his long missing wife.—IPH
