Question

what are some clues that led to finding the blue carbuncle

Answer 1

Answer:

Holmes and Watson were tracking the path of the sale of the goose. As they left the shop of the salesman, Mr. Breckenridge – a small man came to the shop. From the way, Mr. Breckenridge was shouting at the man. Holmes learnt that the man had been repeatedly asking Mr. Breckenridge about the geese that his sister had sold to Mr. Breckenridge. This gave Holmes a clue that the small man knew something about the gem and the goose.
