Assignment Helene

Description for ASSIGNMENT HELENE by Edward S Aarons: 

A WORLD OF MENACING SHADOWS, OF WHISPERED LIES

Durell knew he was in danger. But danger, in his business, was something you accepted daily, like the sunrise. Durell was the sort of man who never turned a corner or opened a door thoughtlessly. He had lived with danger ever since beginning his work in K Section of the C.I.A, and it had gone on longer than he care to remember.

Durell never went anywhere without knowing first whether he was being followed. He had a sixth sense about curious, hostile, watching eyes.

Now he knew immediately that he was being followed, and that once more his life was at stake.

This is #9 in A Sam Durell Novel.
