D-99 - H B Fyfe - Bog

It's a big, bad galaxy out there, and there are plenty of ways for Earthmen to fall afoul of the local natives. Whether its by crash-landing on an alien world, violating the customs of a puritanical religion, ending up as a specimen in an inverted aquarium, or reasons unknown, Earthmen could find themselves imprisoned on an alien world with no way out. But when that happens there is one agency they can turn to, the super-secret D-99. A small group of men and women who one way or another attempt to rescue those who normal diplomatic means have failed. Though, technically, they don't even exist, you can always count on... D-99!
