Dr. Percy Trevelyan seeks Sherlock Holmes' assistance in deciphering his benefactor's recent odd behavior. Trevelyan recounts that some years before, Mr. Blessington plucked him out of an obscure and virtually non-existent practice and offered to set him up at a prestigious address. In return for this investment, Blessington would receive a percentage of his income and would provide him with free medical care. For quite some time now the arrangement has worked well for both parties and Blessington has profited from the arrangement. Recently however, Blessington has been acting very strangely. Having read of a burglary in a nearby home, Blessington was overwrought and had bars installed on all the windows. Holmes is intrigued by the case but subsequent events soon have him investigating a murder. Written by garykmcd

Interesting episode features Nicholas Clay in a strong role...
24 October 2009 | by Neil DoyleSee all my reviews

I admired NICHOLAS CLAY in the film version of EVIL UNDER THE SUN, a good adaptation of the Agatha Christie novel and always wondered why his career on the big screen never really took off.

Here he is Dr. Trevelyan who seeks the advice of Sherlock Holmes (JEREMY BRETT) and Dr. Watson (DAVID BURKE). Seems he has acquired a benefactor who sets him up for practice when he's down and out, and helps him set up his business in fancy surroundings. But his benefactor is a man of quirky behavior and fears and phobias and is hiding a terrible secret--which is eventually revealed by Holmes, of course.

PATRICK NEWELL is the odd benefactor whose eccentric behavior becomes the centerpiece of the mystery.

Well done episode has a compelling story to tell and does it well.
