from the back cover:
In EDI (the European Department of Intelligence in Brussels) there are some very secret files - the Omega Files. There are strange, surprising, and sometimes horrible stories in these files, but not many people know about them. You never read about them in the newspapers.

Hawker and Jude know all about the Omega Files, because they work for EDI. They think fast, they move fast, and they learn some very strange things. They go all over the world, asking difficult questions in dangerous places, but they don't always find the answers . . .
