Colin Templer

Colin Templer is a seventeen-year-old student at Eton. He is almost eighteen. He is searching for Mr. Dunworthy at the start of the novel because he wants to travel back in time prior to Polly Churchill returning from her time travel trip to World War II. Colin has jumped into the time travel mechanism before to travel back in time without Mr. Dunworthy's permission. In that instance, however, Colin was able to save Dunworthy's life and the life of another person.

Mr. Dunworthy

Mr. Dunworthy is an historian. He seems to be in charge of the history program at Oxford in 2060. It appears that Dunworthy is specifically responsible for the time travel studies of third year students that are at least twenty years old, sending them back at different periods in history for research purposes.

Mr. Dunworthy forbids Colin to time travel because Colin is too young...
