Only When I Larf — Len Deighton

Three con artists are on the make, and making millions. There's Silas, the leader, slick and self-assured; Liz, his glamorous lover; and Bob, the young cockney upstart (who's also falling for Liz). As this uneasy trio's swindles take them from New York high-rises to sixties London, corrupt governments to, finally, the ultimate con in the Middle East, will their luck start to run out?
