Ashes
Ashes is a laboratory thriller framed as Malcolm Bruce’s confession to his friend Prague. A professor develops a liquid that reduces matter to ash, then prepares an experiment involving his assistants. Bruce believes his fiancée has already been killed and turns the invention against its maker. Prague’s return to the laboratory reveals that the visible clues did not mean what Bruce assumed.

Publication and narrative frame
The story by C. M. Eddy, Jr., with Lovecraft's involvement, appeared in Weird Tales, volume 3, number 3, March 1924, on pages 22–24. The project catalog dates its composition to 1923.
Prague narrates the framing encounter. His distressed friend Malcolm Bruce arrives and gives an extended account of events in Professor Arthur Van Allister's laboratory. Prague knows the professor and helped him plan the soundproof workroom, making him more than an entirely unconnected listener.
The distinction between speakers matters at the turning point. Bruce believes he has reported an established murder; Prague recognizes that the account contains an inference that still needs to be tested.
The assistants and the secret workroom
Bruce takes employment with Van Allister after losing his previous position. His college experience in chemistry makes him useful as an assistant. Marjorie Purdy, initially employed for secretarial work, also displays substantial practical ability and interest in the laboratory.
Van Allister partitions his workspace and increasingly excludes both assistants from a private series of experiments. Their work together develops into affection and an engagement while his isolation grows.
The arrangement joins a romantic plot to scientific secrecy. Marjorie is not merely a visitor who wanders into danger: she is already part of the working environment and understands what the professor's demonstration means.

The demonstration and its threatened consequences
Van Allister shows the assistants a colorless liquid and demonstrates it on a rabbit in a glass enclosure. The animal is rapidly reduced to white ash. He claims that glass alone resists the substance and imagines its military capacity to erase almost any material obstacle.
The story does not present a chemically credible formula or a real procedure. The liquid functions as a fictional discovery whose essential properties are established by the demonstration and later reversal.
The professor's delight contrasts with the assistants' horror. His first concern is the scale of his achievement and the fame it promises; the suffering of a living subject becomes incidental. This difference in judgment prepares the move from laboratory spectacle to personal threat.

The disappearance and the misleading jar
Marjorie disappears while Bruce is briefly away on an errand. Her outdoor clothes also seem to be missing, and the servants cannot tell him where she went. As the day passes, his anxiety grows.
When Van Allister summons him that evening, Bruce sees a large glass vessel containing the same kind of liquid, a jar of white ash and Marjorie's hat and coat. He immediately concludes that the professor has killed her.
The narrative gives readers the grounds for his inference but does not make them conclusive. The presence of clothing and unidentified remains can support a frightening possibility without proving that the missing woman is their source. Bruce acts before receiving an explanation.

The killing of Van Allister
Bruce attacks the professor. During the struggle Van Allister forces him toward the glass vessel, but Bruce strikes him with the jar and renders him unconscious. Bruce then places the professor in the liquid, which leaves only ash.
The act combines immediate danger with retaliatory belief. Bruce has been threatened during the struggle, yet his account of what follows is driven by his conviction that Marjorie is dead. The story does not depict a formal investigation or a later legal judgment resolving his responsibility.
After leaving the house, Bruce is overcome by what he has done and seeks Prague. His claim that almost no evidence remains reflects the same property of the invention that made Marjorie's supposed death impossible to verify at a glance.

Prague’s objection and Marjorie’s account
Prague asks whether Bruce actually knows that the ashes were Marjorie's. The question reveals that Bruce never heard the professor identify them. The two men return and search an adjoining storage room.
They find Marjorie alive but unconscious in a chest. Once revived, she explains that Van Allister had restrained her and demonstrated the substance on a large dog. The jar therefore contained the dog's remains.
The professor intended Bruce to be the human subject and Marjorie to witness the experiment. He concealed her after she fainted. Her clothing remained in the workroom because she had taken it there expecting an ordinary errand.
The disclosure corrects Bruce's specific assumption without making the professor harmless. The planned crime was real, but its intended victim and stage of completion differed from what Bruce believed.

The final image and the story’s limits
When Marjorie asks where the professor is, Bruce answers by letting ash run through his fingers. The action closes the story without a spoken explanation or a subsequent account of police, trial or marriage.
The repeated ash changes meaning across the plot: proof of the discovery, an apparent sign of Marjorie's murder, and finally the professor's own remains. The substance removes distinctions between bodies, making interpretation depend on testimony and sequence rather than appearance alone.
No named Mythos deity, alien civilization or forbidden book causes the events. The connection to the wider encyclopedia lies in experimental power, secrecy and the treatment of people as material for discovery. Reading it alongside The Last Test can illuminate those themes without turning the two laboratories into one fictional institution.
