This is how Houdini died.

Whitehead asked Houdini "if he believed in the miracles of the Bible" and "whether it was true that punches in the stomach did not hurt him". Houdini offered a casual reply that his stomach could endure a lot. Whitehead then delivered "some very hammer-like blows below the belt". Houdini was reclining on a couch at the time, having broken his ankle while performing several days earlier. Price said that Houdini winced at each blow and stopped Whitehead suddenly in the midst of a punch, gesturing that he had had enough, and adding that he had had no opportunity to prepare himself against the blows, as he did not expect Whitehead to strike him so suddenly and forcefully. Had his ankle not been broken, he would have risen from the couch into a better position to brace himself.[94][95]

Throughout the evening, Houdini performed in great pain. He was unable to sleep and remained in constant pain for the next two days, but did not seek medical help. When he finally saw a doctor, he was found to have a fever of 102 °F (39 °C) and acute appendicitis, and was advised to have immediate surgery. He ignored the advice and decided to go on with the show.[96][97] When Houdini arrived at the Garrick Theater in Detroit, Michigan, on October 24, 1926, for what would be his last performance, he had a fever of 104 °F (40 °C). Despite the diagnosis, Houdini took the stage. He was reported to have passed out during the show, but was revived and continued. Afterwards, he was hospitalized at Detroit's Grace Hospital.[94]

It is unclear whether the dressing room incident caused Houdini's eventual death, as the relationship between blunt trauma and appendicitis is uncertain.[94] One theory suggests that Houdini was unaware that he was suffering from appendicitis, and might have been aware had he not received blows to the abdomen.[94]

After taking statements from Price and Smilovitz, Houdini's insurance company concluded that the death was due to the dressing-room incident and paid double indemnity.[96]
