"The Adventuress: A Craig Kennedy Detective Story" by Arthur B. Reeve is an early 20th-century mystery centering on Craig Kennedy, a brilliant scientist who uses his knowledge to solve crimes, in this case the murder of Marshall Maddox, a rich man who made his fortune in munitions. The story is full of suspense and lies, exploring themes of people stabbing each other in the back and how personal lives can affect big events, especially looking at Maddox’s separated wife, her brother, and a puzzling dancer. The story kicks off with a bang—literally, a gunshot—interrupting Kennedy and his buddy in the lab, soon followed by Maxwell Hastings, who is worried and brings news of Maddox’s death after a tense meeting on a boat. Hastings tells Kennedy that there were problems in the family, big money was at risk because of a new invention called the telautomaton, and that everyone involved had something to hide, suggesting a tangled web of secrets. The stakes get higher when Kennedy finds out that a briefcase with important plans is missing, making him wonder who among the family is involved in the crime, laying the foundation for a puzzling mystery.
