Ranpo bumps into Edgar Allan Poe at an observation deck. Upon their meeting, Ranpo asks for Poe's help in finding Fyodor's right-hand man and the evidence suppressor responsible for framing Kunikida for a murder of a child false military papers that tricked Ranpo. While waiting for the evidence suppressor to appear, Poe shares the mystery novel he was reading wherein the piece's author was killed with the same method on the novel he was writing. After checking the mystery novel himself, Ranpo decided to find the culprit behind the author's murder.

Case
Ranpo reveals that the culprit has two motives - grudge and money and the culprit is someone close to the victim. The culprit learned the content of the last chapter before it was completed and the reason for murder was to make more money and sell it to someone, who turns out to be Poe. The manuscript was sold at an auction with Poe buying it with a prize of twenty-million yen. The two soon stumbled upon the red envelope where the manuscript is contained in.

Just then, the evidence suppressor they were supposed to find appears in front of them, falling from the observation deck. Shortly after, Minoura and his assistant arrive at the scene.

However, Ranpo throws a fit stating that walking is a pain. Shortly after, Mushitarō's work associate arrives however Ranpo also rides the car himself without permission and instructs the driver to get him to the Armed Detective Agency.

While en route, Ranpo shares that he is a detective and is solving a case about a framed coworker who died by falling. Ranpo reveals that the case is tough since the culprit has an ability that can alter reality. Ranpo went on with his deduction stating the culprit killed the author of the manuscript which was sold to Poe, in order for Ranpo to think the evidence suppressor he was pursuing is dead. Ranpo then reveals the evidence to Mushitarō, the last page of the manuscript hidden in a gift shop found by Ranpo. Mushitarō asks him how did he find his last page but Ranpo asks his name to which Mushitarō replied. Ranpo reveals that the culprit behind the author's murder and the coworker's death is Mushitarō.

Resolution

Mushitarō is then contacted by Ranpo and then transported into a novel when the murder took place. Ranpo reveals that Mushitarō killed the author and it wasn't murder but a case of suicide. Mushitarō merely killed the author in order to fulfill the author's wish of creating a perfect murder scheme. After some thought of fulfilling his friend's wish of not revealing the scheme, Mushitarō turns himself in to the police. Ranpo also burns the final page of the manuscript.
