|summary=When Nigel Williams first really burst on to the best-seller list, a couple of decades ago, it was with a book set in Wimbledon that really quite tickled a younger me – and my mother. But then he produced two more in the same series, and we soon decided he was a bit of a one-trick pony, and could never be sure how much of the trilogy we'd read, or be too eager to read more. Flash forward, and Williams has certainly branched out – his setting this time is Putney. Wimbledon Common is now Putney Heath, and so on. But here he provides an epistolatory novel – and if there's one kind of novel to make me prick up my ears it is one built from letters. It is the blatant two-and-fro timing of the narrative, and the succinctness that characters are formed with, that strike me as obvious benefits of such a book – and Unfaithfully Yours has those and many more.
