Question

why did mr otis wish to give the jewels back to lord canterville

Answer 1

For Mr. Otis the jewels were too priceless and they belonged to yhe high dignity of the British aristocracy. They looked out of place in the possession of those people who had been the product of Republican simplicity. Above all, being the legal descendent of Sir Simon, the jewels were the property of Lord Canterville. Keeping these points in consideration Mr. Otis offered the jewels back to Lord Canterville.
