The Problem of Cell is a short story by Jacques Futrelle. It was first published in 1905 and later collected in The Thinking Machine (1907), which was featured in crime writer H. R. F. Keating's list of the 100 best crime and mystery books ever published. Like Futrelle's other short stories, The Problem of Cell features Augustus S. F. X. Van Dusen as the main character, although most of the story is seen through the perspective of a prison warden. While in a scientific debate with two men, Dr. Charles Ransome and Alfred Fielding, Augustus, The Thinking Machine, insists that nothing is impossible when the human mind is properly applied. To prove this, he agrees that he will take part in an experiment in which he will be incarcerated in a prison for one week and given the challenge of escaping.
