Mr. White's final wish was likely to make his risen son's corpse be returned from where he came.
Explanation:
In the story of "The Monkey's Paw" by William Wymark Jacobs, the character of Mr. White had acquired a monkey's paw that supposedly has the ability to grant three wishes. But this granting of wish also has repercussions on the person.
Mr. White had gotten hold of a monkey's paw from his friend Major Morris who had gotten the item from his time in India. But warning him that while it is capable of granting wishes, it also brings disaster alongside it, for the wish is granted in exchange with something. Not heeding the advice, he kept it anyway. Once the friend had left, his son urged him to make the first wish- 200 pounds to pay for the final mortgage payment. This came true but at the cost of his son's life. Then the second wish was influenced by his wife- to ask for his son to be back. The thought of his son Herbert coming back from the dead, mangled and after being buried for ten days, was too much for him so he wished that whatever thing that was knocking on their door be taken back. It's not clear whether the person knocking the door was indeed Herbert or not, but the knocking stopped once the wish was made. So, it is likely that Mr. White's final and only wish was for his "supposedly" risen son to return back from where he had come.
