Since bursting forth on the page in 1887, magnifying glass in hand, Sherlock Holmes has been depicted on screen more than 250 times, gaining him the Guinness Book of World Records title of "most portrayed literary human character in film & TV." Benedict Cumberbatch is the latest to try on the famous detective's deerstalker hat in the BBC's contemporary adaptation, Sherlock. Tin Pan Theater offers free screenings of the show on Sunday evenings, paired deliciously with the English countryside series, Downton Abbey. While Sherlock and Dr. Watson are out on the London streets digging up terrorists' plots, the residents of Downton eavesdrop on each other's conversations like nobody's business, keeping secrets and spinning webs all up and down this upstairs-downstairs drama. Sun. 9 pm (Downton) & 10 pm (Sherlock). Tin Pan Theatre. Free.
