A purposely complicated murder mystery where everyone is a suspect including the two men trying to solve the case! Everyone looks suspicious, everyone acts suspicious, of motives there are far too many. People keep popping up with grudges and valid reasons for wanting a vicious old coot (William V. Mong as crazy Uncle Henry Carson) deader than a doornail. The old geezer is found stabbed. "He died instantly....or very nearly so." The niece (Irene Ware as Elsa Carson) looks to be the prime suspect when the murder weapon and a disguise are discovered in her room. Her motive is well known, Uncle Henry didn't want her to marry Jim Landis (Ray Walker), a detective who shows an unreasonable willingness to solve the case and clear his fiancée. Things look mighty bleak when a second murder victim is discovered under the desk. It's a mouse that detective Landis quickly sticks in his pocket!!! Who could have killed the poor rodent and why-why-why? Is it Foot the Butler (E.E. Clive), a scientist who works with poisonous gasses, or Elsa's Aunt (Hedda Hopper), who admits "I'm a good hater." As if that wasn't nearly enough to contend with, they toss in a case of arson for good measure.Let's just say I stopped guessing early on and just watched the case unfold through a series of interrogations. It was fascinating and entertaining (I was beginning to think they all did it or else the old geezer stabbed himself in the back just to throw them off).
