A detective story unfolds as two friends, one a forensic expert, investigate the mysterious death of Martin Rowlands, a collector of antiquities. Rowlands is found dead in his study, apparently from cyanide poisoning, shortly after acquiring a valuable artifact—the seal of Nebuchadnezzar. The circumstances surrounding his death raise suspicions of foul play, particularly due to the significant insurance policy on his life. The investigation reveals that Rowlands had recently become embroiled in a dispute over the seal, which had a complicated provenance involving a soldier, a dealer, and wealthy collectors. As the detective examines the scene, he notes peculiarities in the footprints and the walking sticks of those who visited Rowlands, leading to the conclusion that one of the visitors may have been involved in the murder. The detective's meticulous observations uncover that the stick left behind by a visitor was not suited to the person who carried it, indicating a left-handed man using a right-handed stick. This detail, combined with the footprints, suggests a connection to the deceased. The investigation leads to the dealer who sold the seal, revealing a web of deceit and greed. As the plot thickens, the detective deduces that the seal was likely hidden within a plaster bust, which is later shattered to reveal the artifact. The dealer, caught in the act, collapses in shock, while the evidence mounts against him. The case culminates in a trial where the detective's findings, including the analysis of the stick and footprints, secure a conviction. The narrative emphasizes the importance of observation and deduction in solving crimes, showcasing the detective's ability to piece together seemingly unrelated clues to uncover the truth behind Rowlands' death and the theft of the seal.
