Margaret Millar’s latest book — which comes after a break of six years — is another superb example of the fusion of the novel of character and the puzzle of suspense. If it were not about a crime, it would still be an absorbing account of people, precisely studied and perfectly placed in their unfamiliar setting. That setting is a remote ranch on the border between California and Mexico. Robert Osborne inherited the ranch when his father was killed while driving a tractor: his father was usually drunk anyway, and no one was surprised that he’d had an accident. But now Robert has been missing for over a year, and is presumed dead by everyone except his doting mother. Robert disappeared not long after he had been on a trip to New York, from which he had returned with an attractive young wife. There doesn’t seem to be much doubt about what happened. A lot of blood was found on the floor of the bunk-house where the itinerant Mexican laborers were lodged, and all the laborers were missing. Plainly, they were responsible, and Robert must be dead. That’s how the sheriff sees it, and the ranch foreman, and Robert’s young widow, and Robert’s lawyer. Only Robert’s mother holds out, opposing the public hearing which the widow, Devon, is now demanding to legally establish his death. But the solution is not at all the expected one; and after it has been reached, Miss Millar has a startlingly macabre ending in reserve. It’s compulsive reading, and beautiful writing
