The Bad Book Affair features the magnificently hapless Israel Armstrong - the duffle-coat wearing, navel-gazing Jewish librarian who solves crimes, mysteries, and domestic problems whilst driving a mobile library around the north coast of Ireland. In The Bad Book Affair Israel finds himself on the verge of his thirtieth birthday and on the trail of a troubled missing teenager, the daughter of a local politician. Why has the young woman disappeared? Does it have something to do with Israel's lending her A Clockwork Orange and Lady Chatterly's Lover from the library's special `Unshelved' category? Will the young woman's father run Israel out of town? How will Israel recover from his own break-up with his girlfriend, Gloria? And how exactly does a Jewish vegetarian celebrate his thirtieth birthday in Tumdrum? With a bacon scone? And will Israel and his irascible companion Ted ever agree about anything?
