Sherlock Holmes gets the rodent treatment in this mystery tale (should that be tail?) based on the children's book Basil of Baker Street by Eve Titus. Aided by the trusty Dr Dawson, Victorian super-sleuth Basil is hired by the daughter of a mouse toymaker who has been kidnapped. Inevitably, the trail leads to Basil's arch enemy Professor Ratigan. The dirty rat, voiced by Vincent Price, wants to force the toymaker to build a fake Queen who will grant him great powers to become ruler of Britain’s mouse population. An animated adventure with all the trappings.
