Retired police captain Waverly Underhill and his sidekick, Doctor Scofield, unmask the murderer in two spine-tingling mysteries. Heard on public radio, each is a contemporary tale in the classic tradition of The Shadow, with a full cast, original music, and sound effects.

A literary flashback combining the creations of Charles Dickens (A Christmas Carol) and Erle Stanley Gardner, this courtroom melodrama poses the questions: What if Ebenezer Scrooge was murdered, found strangled in his bed with a bell cord knotted around his neck and a stake of holly driven through his heart? And what if the man charged with the crime was his own employee, Bob Cratchit?

For Dickens, these performances have become something of an obsession.

A premonition of murder leading to violent death…voodoo, séances, automatic writing and psychic messages from the dead are all elements in a strange case that turns criminal. A worried Doctor Scofield calls in his friend, Captain Waverly Underhill, to unravel the mystery.

About “The Final Case,” Doctor Scofield, Captain Underhill’s personal physician, comments, “A most interesting case study. It is both sad and ironic that the mental affliction Captain Underhill used to pretend to suffer from: that of being senile, was ultimately the very thing that laid him low. And yet, in the annals of crime solving, if this final case does nothing else, it proves the kind of natural-born sleuth my good friend, Waverly, was.”
