Guy Kibbee ("O'Leary") and Aline MacMahon ("Nurse Sarah") are clearly having some fun in this amiably entertaining big house murder mystery. The story centres around a dying old millionaire who finds his grasping family assembling to see what they are going to get! When the butler is killed, everyone starts pointing fingers, and it falls to these two to, rarely in conjunction and frequently despite themselves, get to the bottom of things. It doesn't hang around, there is plenty of quick-witted dialogue and though the plot - there are twins involved, which is always a bit of a giveaway - is maybe not the most taxing, it does end quite quirkily and I rather enjoyed it.
