Carol’s friend Oscar, a retired doctor, discovers a dead man outside an old run down cottage while on his morning stroll. When the police show up, the body has mysteriously disappeared. Oscar is infuriated that the police don’t believe him, and he asks Carol to try to find out what really happened.
Starting with a telephone number that she finds on a small piece of paper where Oscar found the body, Carol is soon in the midst of a sinister mystery involving much more than a missing dead body.
