The Time Police are accustomed to jumping to the past. This time, however, the past has come to them. What connects a dead dinosaur with Romulus the founder of Rome, a shocking cover-up at TPHQ and a plot to murder the Princes in the Tower? The Time Police are determined to find out, helped - and occasionally hindered - by a wayward member of St Mary's and a recently reunited Team 236. Each in their own unique way, obviously. As if all that wasn't enough - something somewhere in the Timeline is wrong. Very, very wrong. What is the Time Map trying to tell them?Can the Time Police find the answers before Time runs out?
