Twelfth century warrior-turned-monk Brother Cadfael (Derek Jacobi) tackles another murder mystery in the 90-minute drama "The Sanctuary Sparrow." A prominent goldsmith is robbed and murdered during his son's wedding. Accused of the crime, traveling juggler Walter (Roy Barraclough) takes refuge in Shrewbury Abbey. Believing in the juggler's innocence, Cadfael uses his scientific know-how to scrutinize the clues at hand -- and comes to the unpleasant conclusion that the actual murderer is someone he knows all too well. Adapted by Russell Lewis from the novel by Ellis Peters, "The Sanctuary Sparrow" aired in England on June 5, 1994, then ran in the U.S. as part of the PBS anthology Mystery.
