But none of this is what's on Lindstrom's mind at all. He believes that Miss Parsons has been snooping in his desk's secret drawer. The only items of importance were a letter from his grandson saying he was finally coming home for a visit (or possibly to stay, he's not quite clear on that topic)....and the combination to the safe where Lindstrom keeps $25,000 in cash. Lindstrom wants to prosecute her for breaking into the desk--but Murray says there's no proof and the most Lindstrom can do is give her notice and change his combination.
The next morning, Lindstrom is found shot in the head and Miss Parsons is missing. So, naturally, the police suspect that she's responsible for the murder. But that theory goes to pieces when she is found shot as well and the $25,000 is missing from the safe. Soon, Camilla's brother Eric arrives, a mysterious man is seen wandering the grounds, and an old friend of Eric's also shows up. The chauffeur's young daughter has been keeping her eyes open and is full of information for Murray and the police--including an identification of the mysterious man. He looked just like Eric! If Eric hadn't been verified as a passenger on that train, he'd be a suspect as well. Camilla's flying skills and the journey of the sleeper train her brother arrived on both play an important role in solving the mystery.
This is a fairly well done mystery plot from the Golden Age. A bit predictable perhaps for those of us who read these things by shelf-fulls, but entertaining. The sub-plot of aviation and romance (between Camilla and Pete) is diverting without being distracting. The characters are decent--with the chauffeur's daughter Ruth stealing scenes whenever she appears. ★★★
