"The fly fell down." Quiller sent the message off to London as requested. He had just seen a supersonic jet plunge 60,000 feet to its destruction. It was the 36th crash, and more were to come-unless Quiller finds out who is to blame.

That meant entering the deadly shadow world between East and West, where the name of the game was betrayal and the stakes were sky-high.

"If you are a Quiller fan this is for you. If you have never met him, it's time you did." (Charleston Evening Post)

At the Tango briefing Quiller got his orders. Orders that sent him on a bizarre undercover operation, a double-suicide mission in the Sahara. His assignment: find and destroy a mysterious downed aircraft before the world learns of its existence, before its cargo is disclosed, and before enemy agents destroy the plane and possibly Quiller along with it!

"Breathless excitement mounting to a screaming crescendo…a real stemwinder…the action is fast and deadly!" (Publisher's Source)

Quiller is back-still working without gun, cover or contacts-behind the Iron Curtain, hiding in a city where there is no place to hide. Trusting in a woman who can't be trusted. Rescuing a man he would rather kill. Trying to save a world that is already heading over the brink.

Quiller is "the greatest survival expert among contemporary secret agents." (The New York Times)

Adam Hall is "skillful as ever at stretching suspense to the screaming point." (Publishers Weekly)
