It would appear some fiendish creature is once more at large on Dartmoor and has, like its predecessor, targeted the unfortunate Baskerville family. 

This program includes a preface read by the author.

Under his reluctant tutelage, this very modern 20th-century woman proves a deft protégée and a fitting partner for the Victorian detective.
