In order to foil an assassination plot, counter- agent Matt Helm must undertake his most dangerous mission: matrimony. A man like Helm is not the kind a woman would marry. Unless she has to. Unless it's all part of maintaining an ingenious cover. The man whose daily bread is violence takes a most unlikely brideâjust to make sure death doesn't part them.
