Art director: Stanley Fleischer. Gowns: Howard Shoup. Music: Howard Jackson. Dialogue director: John Langan. Sound recording: Leslie G. Hewitt. Producer: Bryan Foy. A First National picture.Copyright 23 December 1937 by Warner Brothers Pictures, Inc. New York opening at the Palace: 28 June 1938. U.S. release: 21 May 1938. 56 minutes.SYNOPSIS: The daughter of a murdered millionaire (who supposedly committed suicide) summons to the family hunting lodge all the people who were there on the fateful occasion.NOTES: Sixth and final entry in the Sarah Keate series. An odd series for a number of reasons. In Eberhart's novels, Sarah Keate is a middle-aged, spinster nurse. Aline MacMahon was an ideal choice for the role in the first of the series, While the Patient Slept. For the second movie, however, Sarah was not only made younger but underwent a name change to "Sally Keating". Marguerite Churchill continued this trend in the third film, Murder by an Aristocrat. Would you believe, in the fourth film, the character reverted to middle age and was played by Jane Darwell? But for the fifth and sixth entries, Sarah/Sally became young again in the person of Ann Sheridan. COMMENT: A confused and confusing mystery thriller that involves so many characters milling around in such a short space of time, it's virtually impossible to keep track of who's who, unless you see the film twice! Unfortunately, it's hardly worth a single once-over. Ann Sheridan fans will be most disappointed. Not only does their idol contribute a perfunctory performance, she spends what little footage she has in a dowdy nurse's uniform. The actual feminine lead is Anne Nagel, but she too seems somewhat bland and colorless. It's left to Elspeth Dudgeon to hold up the distaff end with her Dame May Witty impersonation from "Night Must Fall". On the male side of the ledger, Dick Purcell makes a tepid hero and Trevor Bardette an unconvincing domestic. Only Ben Welden fitfully shines. Director Noel Smith does little to earn his pay but keep the jumbled events moving steadily towards the fade-out.

"Mystery House" is another film with Sarah Keate / Sally Keating where the nurse (here working privately, in the service of a grouchy old lady in a wheelchair) is involved in a murder mystery but, just like in "The Murder Of Dr. Harrigan", does no amateur sleuthing herself, as I had been led to believe; the detective duties are handled by a professional in the field, her private investigator boyfriend. The film is notable for a clever solution to its "locked-room" puzzle, but the supporting characters are played by largely unknown or forgotten today actors, and it's difficult to tell some of them apart; three of the men look almost exactly alike! Despite an ideal setting (an isolated and snowbound hunter's lodge), "Mystery House" is a middle-of-the-road entry in the genre. ** out of 4.

I was pleased to see that more than a few folks here on IMDb knew who Mignon G. Eberhart was. "Mystery House" was based on one of Eberhart's 'Nurse Keate' stories. In a nutshell, these stories are all murder mysteries, all use a medical pretext as a plot springboard, and all feature a hospital nurse, Miss Keate, plus a detective named Lance O'Leary (Dick Purcell, in this outing). Ann Sheridan was the only actress to portray Nurse Keate more than once; --her other showing was in "The Patient in Room 18" --a weaker entry, which starred Patric Knowles as Detective O'Leary. The weakest Keate has to be Marguerite Churchill, who was called 'Nurse Keating' in "Murder by an Aristocrat." As good as Ann Sheridan was as Nurse Keate, she was easily bested by Aline McMahon's turn as the sleuthing nurse in the Warners' Eberhart story, "While the Patient Slept." Even though Eberhart's characters appeared in several films, it would probably be inaccurate to describe these films as a "series." In "While the Patient Slept," Guy Kibbee played the oldest O'Leary of them all, --however, he filled the part with character and gusto, --traits that both Dick Purcell and Patric Knowles lacked.Most of those who commented here, appreciated the film's supporting cast, but largely didn't know who any of them were. I also liked the supporting cast, and think it's worth mentioning some of those actors here.---1)-William Hopper, who would later become known for his 9-year stint as Paul Drake, in the Perry Mason TV series on CBS. 2)-Anne Nagel, a beautiful actress who never rose above B-movie roles (such as this one). She appeared in films such as "The Mad Doctor of Market Street" and "Murder in the Music Hall.". Nagel also had a Perry Mason connection, although not to the TV series. She appeared as Janice Alma Bromley (the "fake Janice") in the Mason film, "The Case of the Stuttering Bishop." 3)-Ben Welden: A "tough guy" in hundreds of films and early TV shows, Welden specialized in playing hoods, --often as comic relief. In "Mystery House," it's Welden's toupee that figures in the plot. A steady worker, Welden had parts in at least 18 films in 1938 alone, the year of "Mystery House." Some of his 1938 output included: "Smashing the Rackets" "Crime Ring" "The Saint in New York" and "Time Out for Murder." In early television, Welden racked up multiple appearances in programs such as "Space Patrol" "The Lone Ranger" and "The Adventures of Superman." 4)-Dennie Moore, --a marvelous supporting actress, who's Jersey accent kept her typecast in films. She was often cast as a maid, or a shop-girl, or as a 'comic sidekick' to the heroine. Moore is best remembered for her brief (though, pivotal) role as Olga the manicurist, who "spills the beans" to Norma Shearer's character in the 1939 blockbuster film, "The Women." 5)-Elspeth Dudgeon, the elderly actress who played the wheelchair-bound aunt in "Mystery House" was a true wonder to behold. Though often seen in very small parts, where folks cannot remember her name, many viewers marveled at her role as Ernest Thesiger's father, the bedridden Sir Roderick Femm (yes-- she played a MAN - with whiskers!) in "The Old Dark House." In that film's closing credits she was billed as "John" Dudgeon! Personally, my fave screen appearance by Ms. Dudgeon was in Warner Brothers 1936 B-mystery-comedy, "Sh! The Octopus." If you haven't seen it, I won't spoil it for you. I will, however, say that Dudgeon simply steals the movie, near it's climax. Other supporting-actors who appeared in "Mystery House" include Sheila Bromley, Eric Stanley, and Trevor Bardette (another veteran who has hundreds of screen appearances to his credit). Any discussion of the Nurse Keate films would be incomplete without mentioning "The Great Hospital Mystery" --produced by 20th-Century/Fox, and starring Jane Darwell. While most of the Eberhart/Keate yarns were filmed by Warners, this lone 20th/Fox effort stands out for many reasons. It features a superior cast of supporting actors. In addition to Oscar-winner Jane Darwell, the cast includes Sig Ruman, Sally Blane, William Demarest, Joan Davis, and Thomas Beck. If you're an Eberhart/Keate fan, "The Great Hospital Mystery" is the film you must not miss. It's an atmospheric little mystery, best seen late at night....when you're all alone. --D.--

This high-speed version of one of Mignon Eberhardt's classically plotted mysteries is directed by Noel Smith, one of Warner's experts in short features, timing in at a bit less than one hour. Mr. Smith spent much of the 1930s and 1940s directing second feature westerns and mysteries.Half a dozen people are isolated in a house while the detective tries to figure out which of them, all with excellent motives, committed the murder. This sort of mystery requires a tremendous amount of talking, and people talk fast. Unhappily, most of the dialogue is exposition and delivered a bit stiffly. Visually, it's very nicely done with some excellent tracking shots to maintain good composition and an overall look like an Old Dark House movie. The print, like many of the major studios' B movies of this period, is in excellent shape.Over all, it's a pleasant way for mystery fans to spend an hour with a story that will keep you guessing until the end.
