For only the second time Rathbone's Holmes and Watson are taken out of London (the first was their visit to Washington), this time into the Canadian backwoods.
Some strange apparition appearing in the village, La Morte Rouge (The Red death), kills Lady Penrose. Holmes travels to the village to look into the murder but is met with hostillity from the people. Soon, more murders take place, and the villagers place their blame on the monster of the village.
What follows is one of the darker entries in the series with the worlds most famous consulting detective putting the pieces of the mystery together in an adventure that bares more than a passing resemblence to the earlier "Hound of the Baskervilles".
Definately recommended and I look forward to the day when all of Rathbone's Holmes adventures will be available on DVD.
