Henry T. Butler

In the novel Nemesis, Henry T. Butler is an American tourist. He goes on the Famous Houses and Gardens tour with his wife Mamie.

While the tour group is visiting a Queen Anne Manor House, Mamie says that the room they are in has "quite an atmosphere". Henry proudly tells those around him that Mamie is very sensitive to atmospheres, and begins to tell a story about being in an old house in Louisiana.

After the accident in which Miss Temple is injured, Henry says that he is wondering if they should give up the tour, and not continue with it. He points out that if Miss Temple's injury proves to be fatal, there might have to be an inquest, and they would have difficulty resuming the tour until they knew definitely.

After Miss Temple's death, Henry and Mamie decide to return to London. Mamie says that she feels unsafe, as if at any minute, someone might shoot at them or throw a stone at them. Henry tells her not to let her imagination go as far as that.
