Dr Siri's bagged himself a holiday with his friends - an all-expenses-paid trip to the mountains of Laos. He is to assist a US-funded search for a lost CIA pilot - Boyd Bowry - missing since 1968, though Siri strongly suspects that when the helicopter exploded, the pilot followed suit.

But, just hours into the trip, it becomes apparent that ulterior motives are at work within the group and those associated with the airman start dropping like the insects that frequent the surrounding landscape.

Siri and co are caught up in something big. Something that goes way back and is way over their heads. And, if this wasn't bad enough, a psychic of unquestionable repute then informs Siri that he's about to die - in 'a day or two', to be precise.
