The house ad for the Nick Carter, Killmaster series at the back of this paperback proclaims, "Nick Carter has inherited the mantle of the late Ian Fleming's James Bond." Carter does have some similarities to Fleming's Bond. Carter smokes custom-made cigarettes like Bond does, and Carter's designation as a "Killmaster" by the agency he works for is very similar to Bond's "double-oh" classification that gives Bond the license to kill. But Carter is much more like Donald Hamilton's Matt Helm than Fleming's Bond. Carter is essentially an assassin from the hard-boiled school. His assignment in "Macao" is very Helmsian: He's ordered to walk into a trap and kill the trapper--a high-level Red Chinese intelligence officer. And, on this assignment, he's in the company of the inevitable beautiful, but morally compromised, woman.
One thing about Nick Carter is that he's not nearly as opinionated as Matt Helm. He seems to be a pretty straightforward guy who takes life as it comes. He's not prone to Helm's constant complaints about all manner of things. And Carter doesn't seem to have the problem Helm has with women wearing pants (a complaint that Hamilton's Helm shares with us in virtually every one of his adventures).
"Macao" is taut, suspenseful and builds to an exciting, if gruesome, climax. The political background is a fascinating glimpse into the geo-politics of the late '60s, and the local color provides vivid descriptions of Hong Kong and, of course, Macao.
