Isabel spends her time either jumping to wild and speculative conclusions about these men - one cut a rope allowing a fellow climber to fall to his death and another wrote the suspect letter to improve his own chances. These intuitions are interspersed with ethical musings, such as:
Was it possible that he was ... transsexual. . . . although she, of course, might not be prepared to convert a heterosexual relationship ... into a lesbian relationship with [her] former [lover].Though more ideas than action, similar to much hard science fiction, the story is a fine mystery with logical, but surprising, reveals at the end.
Pleasant light reading for more educated and academic readers.
