• Single-parent upbringing

• He joined the Army when he was eighteen years old

• Nature: a bit cynical and sarcastic. James Cash always attaches the utmost value to the messages sent by his subconscious.

• When we find James Cash back in America a friend of him asks if he is still working for the Agency. 

He answers: " I can’t stand the smell of sewers anymore... "

• When he returned to civilian life, James Cash created a company - with his personal apartment included in the office. He bought it with the help of funds raised during secret missions and which source is inexplicable.

• Recurring nightmare: he remembers a torment in Vietnam and sees the mangrove swamp when the tide was rising around him, crawling with hideous animals under the surface.

• J. Cash : " I want a joker... Billy the kid. "  (Billy Cobb's nickname)

Colonel Kelly : " What? You want the kid to move into the attack?... he has not enough pratical experience. If you are a realist... "

J. Cash : " We get on well together. He is too old to wet the bed. Do you give him to me?"

Colonel Kelly : " O.K... try to keep him out of danger "

• Billy Cobb (James Cash's partner) : " I have permission to stay here as an observer. "

• James Cash : " O.K! You are here as an observer "

• Aboard an helicopter circling over San Diego Bay, James Cash and Billy Cobb (the young FBI " observer ") are tracking invisible mobsters who kidnapped a police woman. To find them, James sharpens his hearing and focuses on a coming and going radio signal transmitted by a beacon far away. The pilot turns several times over the bay, and Cash succeeds in tracing the tonality back it's source :

" We picked up the "bip"... Everybody shut up! I want to hear this signal! It’s our target, fellows..." Cash’s left hand was clenched on Billy’s shoulder who felt the slightest impulses of the latter. As in Santa Monica Mounts a strange frenzy was creeping over Cobb. He was almost able to feel his passenger’s train of thoughts and was vibrating identically.
