"My name is Roger Whiteley, and I'm going to tell you about a couple of murders I got embroiled in recently."

Seventeen years ago, bumbling law student Roger Whiteley and a group of his contemporaries gathered for a pre-graduation party in Cambridge. During the evening they made secret predictions about their futures, which they locked away in a time capsule.

The group, older but not necessarily wiser, reassemble in college to open the capsule on the allotted date, but less than twenty-four hours into their reunion one of them is stabbed to death and the capsule itself goes missing.

As old secrets bubble to the surface it becomes clear that several members of the group are hiding sordid secrets.

What is the meaning of the strange cryptic drawings found with the corpse?

Is there a link to the mysterious death of a college Porter a few weeks before?

Who is the strange bearded man following Whiteley around town?

Whiteley turns for assistance to his former tutor Gerald Sinclair, a criminology professor, amateur detective and self-proclaimed genius with a peculiar set of skills.

The unlikely duo find themselves on a treasure hunt set by a dead man, as they race against time to track down the capsule, solve the crime and unlock the mystery before the killer can strike again.
