Query: Face-paced Shoot-em up

The Cassandra Compact, by Robert Ludlum and Philip ShelbyJon Smith is sent to rescue Yuri Danko, who has called the secure line and asked to be extracted. Danko has a piece of terrifying news, but before he can tell Jon, he is cut down in a spray of gunfire by assassins. Smith deduces that someone is out to steal a sample of smallpox from the Russian cache of bioweapons and perhaps manipulate it to make it more virulent. This is a face-paced, exciting and scary book. Lots of action and shoot-em-up. Not exactly my thing, but I did enjoy it quite a bit.
