Quiller is sent to Bangkok to protect a senior British visitor known only as The Person. The assignment is tied to a threatened assassination during an official visit, so surveillance and timing matter more than a conventional battlefield.

Readers who want the series opening should start with The Berlin Memorandum, which was retitled The Quiller Memorandum in the United States. The 9th Directive then gives Quiller another mission in Bangkok rather than retelling the earlier Berlin case.
