Now he wants both of them back as the daughter must sign for the money which is his real interest. Gregory had adopted the daughter as Jahnchek has never seen her plus she is now engaged to a senator. Gregory also finds himself being blackmailed by Franz Moray, a retired Swiss bank official.

Excellent mystery that produced a great show.
11 September 2012 | by kfo9494See all my reviews

This episode has all the qualities you expect from a 'Perry Mason' show. Good script, interesting characters and a mystery that is entertaining. Made for an enjoyable 52 minutes of viewing pleasure.

It starts off rather strange when Stefan 'Big Steve' Jahnchek has been let out of prison to testify before congress on mob activities. But during a break in the action, Big Steve is able to escape and makes his way to the LA area.

He wants to get in touch with a local fisherman named John Gregory. Big Steve had a baby daughter and John had agreed to care for the baby while Big Steve was imprisoned. Big John had even set us a trust fund for his daughter Helen that included thousands of dollars when she reached the age of 21.

However John tells Big Steve that his child died in an automobile accident which did not seem to bother the convict. All Big Steve is wanting is the thousands of dollars that was in the fund.

John also had trouble from a retired Swiss bank employee that was blackmailing for some secret that John wanted kept quiet. But when the bank employee ends up dead on John's boat all evidence points to John being the killer.

Perry will defend John in court which will produce some interesting results. Inside the courtroom we learn that all may not be what they seem. People identity will be discovered and people's true friendship will be tested. By the time the proceeding end we have learned more secrets than people in the script.

An excellent mystery.
