Of the three young actresses I've seen so far in the role of Sarah Keate / Sally Keating, Marguerite Churchill is my favorite (Kay Linaker and Ann Sheridan were the other two). She makes the most inquisitive and intelligent nurse, and she actually solves the case herself (of course this has more to do with the writers, who made the - amateur or professional - detective of the other films a man). This entire film is well-produced and very well-acted. There is just one small problem: the big mystery is quite obvious. Anybody who has seen more than five murder mysteries in his or her life will recognize the significance of the mail plane, and as soon as you've done that, you'll also know which of the suspects has a totally fake alibi. Any surprises in the film are minor - e.g., who moved the dead body from the study into the library. "Murder By An Aristocrat" is still worth seeing, but for a knockout surprise ending, search for "The Great Hospital Mystery" (which had an older Keate) instead. **1/2 out of 4.
