However, the narco-criminals will kill ruthlessly to protect its operation and even before Sherman can leave Schiphol Airport he has already witnessed the gunning down of his key contact, been knocked half-unconscious by an assassin, and tangled with local authorities.
"Puppet on a Chain" has the standard twisting plot, local atmospherics, and sardonic dialogue that were Maclean's trademarks as a story-teller.
As his investigation is undermined by betrayal, leaving him constantly a half-step behind his adversaries, Sherman must resort to increasingly violent action to turn the tables.
The story culminates in a violent struggle above the streets of Amsterdam to save the life of his surviving female operative, not knowing whether anyone they meet can really be trusted.
[2] MacLean got the idea for the book from visiting Amsterdam with then business partner Geoffrey Reeve who later directed the film version.
