One of Morton Janklow's more challenging clients is Willliam Colby.

"Having spent his whole life not telling anybody anything is an additional disincentive to candor," remarked an associate of the ex-CIA director, who he sat down in his Bethesda home last year to write a memoir for which Simon & Schuster paid over $200,000. His first effort was a series of essays that thrilled no one who read them; as Colby's agent (literary, that is) Janklow urged him to tell a more personal story - "What did your wife feel when you were away for those long periods?" he asked.

That started Colby on the track.

He chose Peter Forbash, a former Eastern European correspondent for Time magazine, to be his ghostwriter.

The book is done - "It starts with falling out of air-planes in World War II and ends as I drive away from the CIA," says Colby, who hopes for spring publication. Today he is two weeks into a public career as a lawyer. The other two partners in Colby, Miller & Hanes have experience in energy, environemnt and occupational safety. "My own background," Colby says, "is of course, international, and I guess you can say to some extent, the information business."
