Published by Heinemann in 1965 at 18/- and almost immediately in a Companion Book Club edition at 5/9. The US edition by Morrow came out in the same year. There was a re-issue in 1971 in the Heinemann uniform edition, and several paperbacks, starting with a Pan paperback in 1967.
This was the first of the four Rex Carver books, which Canning wrote between 1965 and 1968. Len Deighton had published the first of his "cheeky rebel" intelligence thrillers, The Ipcress File, in 1962, and Canning joined the fashion. The first Bond film appeared in 1962 and that, too, may have had an influence.
All the Rex Carver novels are told in the first person (unusual for Canning) and set in locations round London, France, Switzerland and other parts of Europe and the Mediterranean area. Carver is a private detective who never touches divorce, with an office in Holborn staffed by his secretary and working partner Hilda Wilkins. (Wilkins is not his sexual partner, being engaged to a Swedish Suez Canal pilot called variously Harvald and in a later book Olaf.) Carver bets on horses and drinks and smokes heavily, but keeps fit by working out at Miggs's gymnasium. Occasionally he is cajoled or blackmailed into working for the Secret Service by Manston (the hero of an earlier book, The Limbo Line in which Carver does not appear) and Manston's unpleasant boss Sutcliffe.
This book begins with a commission to find a missing girl in Brighton, continues with Carver pursuing her to Paris, Dubrovnik, Venice and Germany, and concludes with the thwarting of an attempt to establish a new Hitler dynasty. There is a large cast of characters with conflicting and changing allegiances. Nobody can be taken at face value. The progress around various European tourist spots is frantic and it is unrealistically easy to make travel bookings, a feature that Canning had already satirised in his essay, "The Trouble with Heroes" in Suspense magazine. The final scene is a magnificent set piece which would make a splendid cinema climax. This may be how Canning thought of it, and he can count himself unlucky that nobody made the film and his work in that genre was eclipsed by the success of the James Bond franchise.
One thing that has changed markedly from Canning's earlier books is the hero's attitude to women and sex. In the previous thrillers the hero has had to rescue, or sometimes be rescued by, a heroine he has just met. There is mutual attraction, but nothing more than chaste kissing can occur before the marriage that we assume follows the ending of the book. A consequence of this is that the pairing is "used up" for plot purposes. It would be too much of a coincidence if that heroine again required rescuing from evil villains. One innovation of Ian Fleming's which Canning now adopts is the re-usable hero, prepared to bed the girl and then discard her in time for the next book. The moral code that Canning wrote by did not allow such behaviour before this book, and even now there is a certain delicacy observed. Carver does not contemplate bedding a girl unless he is "falling in love with her". Lust is not enough. Often a pair are heading towards copulation when there is a handy interruption. By such means the author keeps Carver out of the wedding trap which has caught his previous heroes, although he does allow a month of out-of-wedlock passion during Carver's convalescence at the end of this story, and the girl in question does not reappear in any later Carver book. Carver's sexual morals become freer in the later stories in the series, and he chalks up two or three bedroom encounters per book.
An interesting point to note is that there was no translation of The Whip Hand into German, although every previous Canning thriller back as far as The Hidden Face in 1956 together with several earlier ones had been translated and almost all his subsequent books would appear in German translations too. Clearly the subject of Nazi history and neo-Nazi resurgence was too tricky to include in a thriller for the German market at that time. Incidentally it was and I believe still is illegal to sell in Germany a book with a swastika on the cover, as the first British paperback edition had.
The writing is characterised by rather slick, occasionally plaintive, comments, such as:
"... Beyond the law, you could go deeper still, deep and dark, down below the anemone and coral line where the big security sharks lurked. Down there they've never heard of friendship. Some of them screened their own wives before they kissed them goodnight." (Page 9)
"It's the early worm that catches the bird." Said to a fisherman when Carver has just chatted up Katerina on Brighton Pier. (Page 17)
"What did I learn? ... that there's an office waiting, clients being clever with you, and two roads running away north and south, and that you've got to be honest and take your own road because somewhere at the end of it—with luck—there might be the thing you really want. Or am I just kidding myself? Probably."
