Following the end of his engagement with Sally Wright, Brigadier Lethbridge-Stewart is ordered to the Sanctuary by his commanding officer, General Hamilton. The plan is for Lethbridge-Stewart to have “time alone if nothing else. The Sanctuary specialises in mental strength – new techniques, but they take peace and quiet to learn.” Of course, it isn’t only Lethbridge-Stewart that Hamilton sends, but Sally too. But, naturally enough, the Sanctuary isn’t exactly what it seems and, despite their bruised feelings, Lethbridge-Stewart and Sally find themselves dragged into a new mystery… Based on characters created and inspired by Mervyn Haisman & Henry Lincoln.
