A guest at Horace Derwent’s masquerade ball at the Overlook Hotel in 1945. Roger is dressed in a dog costume, and he is very drunk. When Jack begins to go mad and hallucinate, he sees Roger in the Colorado Lounge, begging for alcohol like a dog begging for a bone. When Danny tries to go down to the hotel’s lobby to talk to Jack before he goes fully insane, Roger—whom Danny sees as a horrifying, bloody dogman—guards the stairs and elevator and won’t let Danny pass. The character of Roger illustrates how multiple eras unfold all at once at the Overlook Hotel, effectively obliterating time—and, as the dogman, he is an example of the paranormal occurrences at the hotel and the power they have to induce terror.
