[2] Strangeways is called in by the reputable publishing house Wenham and Geraldine to investigate a matter concerning a retired general, Richard Thoresby, whose wartime memoirs include controversial criticism of public figures.

Thoresby had agreed to cut the pertinent sections, but they were mysteriously re-inserted during the publication process, exposing the publishers to action for libel.

Suspects for tampering with the manuscript include partners Arthur Geraldine, Elizabeth Wenham, and Basil Rye; recently-sacked production manager Herbert Bates; and Stephen Protheroe, long-time editor for the firm but once a highly-regarded poet.

In a sudden twist, however, Miles is murdered in her office, with evidence suggesting that the killer altered the text of the autobiographical manuscript on her desk.

Strangeways, collaborating with Scotland Yard Inspector becomes convinced that the book tampering and the killing are linked, driven by events stretching back to the 1920s.
