Stars-on-the-downslide Wallace Ford and Marian Marsh briefly rallied in the above-average Monogram melodrama Murder by Invitation. Ford is cast as usual as a wisecracking reporter, this time christened Bob White. Our hero is one of several acquaintances and relatives invited to an old dark house to attend the reading of a will. At the stroke of midnight, one of the guests is murdered?and then another. The most obvious suspect is Aunt Cassie (Sarah Padden), the slightly daft owner of the mansion, but Bob suspects that she's being framed, and with the help of heroine Nora O'Brien (Marsh) he sets about to prove it. Some of the film's best moments are suppled by beetle-browed Herb Vigran, a busy supporting actor whose best professional days were still to come.Murder by Invitation closes with one of those "It's only a movie, folks" gags indigenous to the Monogram product of the 1940s.
