Twenty years earlier, aged seven, young Henry Knight saw his father torn to pieces by a monstrous creature at Dewer's Hollow near their Dartmoor home. Now Henry has seen the footprints of a huge beast and suspects that the nearby Baskerville government research station is breeding mutant animals. Sherlock and John travel to the moor where local lad Fletcher organizes tourist walks cashing in on the legend of Dartmoor's spectral hound. Using false I.D. the pair infiltrate Baskerville and are challenged by secretive Major Barrymore but rescued by sympathetic Dr. Frankland, a friend to Henry. After Sherlock himself sees the monstrous creature he enlists the help of geneticist Dr. Stapleton to help him solve the mystery. Written by don @ minifie-1

User Reviews

Polished, imaginative, plenty of bite.
18 March 2019 | by Sleepin_DragonSee all my reviews

The first two series of Sherlock were quite superb, they hardly put a foot wrong, The Hounds of Baskerville, in my opinion is one of the best. It is such a slick, creative, truly imaginative reworking of Conan Doyle's most famous novel, who's not heard of the blood thirsty hound, that terrifies people on the Moors? This could have easily been a disaster, but it wasn't, it was superb, back then the show was super clever and witty, without being smug.

Plenty of scares and thrills, definitely dramatic enough to keep you fully engaged and entertained.

Superbly acted, Cumberbatch and Freeman on top form, special mentions for Russell Tovey and Amelia Bullmore.

Excellent production values, several scenes from this one lived with me a long time.

I'd class this as excellent. 9/10
