When the Twelfth Doctor was investigating strange events in Edinburgh 1645, he adopted the alias of 'Doctor Robert Louis Stevenson' as there was already a 'John Smith' in Edinburgh at this time (PROSE: Plague City).
In 1828, Doctor Robert Knox alluded to Stevenson's novel The Strange Case of Dr Jekyll and Mr Hyde during a conversation with Evelyn Smythe. Given that Stevenson would not be born until the 1850s, the Sixth Doctor realised that he mentioned the novel as a test for Evelyn whom he correctly believed may be another time traveller.

Another of Stevenson's books was Treasure Island. The First Doctor exchanged Treasure Island for a copy of The Time Machine while visiting Professor Chronotis in Cambridge in 1958. (PROSE: Cambridge Previsited)
