Tightrope for Three

Genevieve's child is ill with appendicitis on a night when the fog makes it impossible for an ambulance to reach them. Fortunately, Genevieve's soon to be ex-husband, Paul, will be flying to London on his helicopter for an emergency board meeting and they can divert to a hospital before flying on. It'll be awkward for them all as Paul's secretary and lover will be on board too, but what does that matter? As it turns out, it doesn't. Not with a desperate murderer turned hijacker who'd rather leave no witnesses behind.
