I just listened to "Jacob’s Hands." This fine drama was performed for the CBS Radio Workshop. The story has been recently released in book form and there was going to be a movie adaptation, but it never materialized. The drama is well-worth a listen. Does Jacob really have the power to heal?
The introduction says it was based on a true story. I haven’t found anything connected, however. It reminds me of St. Rocco.
You can download the episode from this podcast page.
Also, on the Marian devotion side of things, I recommend the 54 day Rosary Novena for serious cases.
