Young Alexander Holmes and his trusty dog, Watson, combine their talents to solve mysteries around their neighborhood. There’s the mystery of the magic lamp; the mystery of disappearing animals at a circus; the mystery of ‘Chew-Goo’ - a sweet to stick noisy children’s teeth together; the mystery of the haunted woolshed; the mystery of the missing skater; and the mystery of Grandpa’s abduction by the ‘Gruff Granny Gang’. Elementary logic and a good nose are the keys to Holmes and Watson’s success.
