Storme Toolis

A mix tape from 1983 is discovered containing the voice of a teenage girl who was murdered shortly after it went into her school's time capsule. Griffin becomes convinced that the girl is reading from a speech secretly prepared for the Queen to broadcast in the event of a nuclear war.

The team investigate the death of a personal trainer who had belonged to a Roman reenactment society and discover a gang selling illegal steroids but the motive for murder may not be all it seems.
