A Traveller in Time by Alison Uttley is a much-loved time-slip novel which vividly captures life at the time of Mary, Queen of Scots. Penelope lives in the 20th Century, and it is only when she visits Thackers, a remote, ancient farmhouse, that she finds herself travelling back in time to join the lives of the Babington family, and watching helplessly as tragic events bring danger to her friends and the downfall of their heroine Mary, Queen of Scots, whom they are seeking to rescue.
