She and Allan is a novel by H. Rider Haggard, first published in 1921. It brought together his two most popular characters, Ayesha from She, and Allan Quatermain from King Solomon's Mines. Allan Quatermain, the swashbuckling adventurer who is H. Rider Haggard's best-remembered character, often faced down formidable adversaries in exotic lands around the globe. But in The Ancient Allan, the perilous journey that Quatermain undertakes is one that leads him into the murky depths of his own distant past, where he learns more about his adventures in a previous existence that took place long ago.
