Pamela slipped in the woods and landed at David's feet, showing a good deal more than a nice young girl would normally show to a strange male. It was a case of love at first sight, but soon the strange and sinister Lost House was to come between them.

Lost House was a fashionable British Columbia retreat for wealthy guests from all over the world, but it was soon obvious to David that a great deal more was going on. He finally unravels the mystery and Lost House turns out to be headquarters for a gang involved in the traffic of illegal narcotics.

But which of the guests is head of the gang? Tension and suspense grow as David tries to answer this question.
