The Canterville ghost develops a number of plans to avenge the indifference of the Otis family. In Chapter Three, for example, the ghost attempts to wear an antique suit of armour, an item which he is intensely proud of because he wore it in a tournament when he was alive. Unfortunately, this attempt fails to produce any fear among the members of the Otis family and causes the ghost nothing but embarrassment.
Later in this chapter, he develops another plan to frighten the family. This time, he will attack Washington Otis, who is responsible for removing the blood-stain, frighten Mrs. Otis by whispering in her ear and then appear as the character of "Dumb Daniel" before the twins. Once again, however, the ghost's plan is a failure and he instead comes face-to-face with "Ye Otis Ghost," a 'ghost' of Washington's creation.
Despite his plans, the ghost cannot overcome the indifference of the Otis family and this contributes directly to his decision to leave Canterville Chase and to rest eternally in the Garden of Death.
