Locked in Cages by Richard Godwin

Therapy cured them of their phobias, but in the glass house, the kidnapper is taking the cure away…

When the adult children of two wealthy families are kidnapped, private detective Earl Blake enters a labyrinth of lies and evasions as he attempts to rescue them. The kidnapper wants money the families can’t come up with, and Earl finds himself in a race against time to find Michael and Abby before it is too late.
