Master Tales of Mystery, Volume 3

Dr. Burnham, a physician who has tended to the reclusive billionaire Stephen Haswell for over a dozen years, is called in one night to examine the tycoon’s sudden, total blindness. The case quickly proves odd, not merely for the mysterious loss of sight but for the uneasy feeling that something more sinister may be at work. Professor Kennedy, a sharp‑witted investigator, urges Burnham to look beyond the obvious and consider who might benefit from Haswell’s misfortune.

Together with Craig, the doctor’s longtime colleague, Burnham studies a fragmented letter from Grace Haswell Martin, the estranged daughter who vanished years ago after eloping with an artist. The note, stitched together from torn pieces, hints at hidden motives, family grudges, and a possible plot to wrest control of the vast estate. As the physician wrestles with his professional duty and personal loyalty, the mystery deepens, inviting listeners to follow the early clues and decide what lies behind the “invisible ray” that may be more metaphor than invention.
