Steed's Library: Spotted Again

I have rather got out of the habit of posting my sightings of the books from John Steed's flat in Stable Mews. I suppose I have got used to the idea that this set of distinctive leather-bound books would keep appearing all over the place in sixties TV (and it's not only the books, props reappear all over the place in The Avengers, and recently I have read about props being used in both The Prisoner and Randall and Hopkirk Deceased). I have got so used to seeing them, that recently it took me aback to see Steed hiding behind his books when pretending to be under the influence of a powerful hallucinogen and chased by a murderous fake nanny who is a diabolical mastermind. Of course the episode could only be Something Nasty in the Nursery.
