Reginald Denny is on good form in this rather formulaic whodunnit as "Oliver Keith" - an accomplished PI drafted in to investigate the killing of a wealthy art dealer. Once on the case, he discovers there is a lot more to the case than just the fatality - and there are no lack of suspects mired in this tale of greed and ambition. What helps this along nicely is the engaging double-play between Denny and his equally competent, if somewhat undervalued, assistant "Ella" (Patricia Farr) and Lew Kelly is quite good as the pretty hapless policeman. Only an hour long, but still a decently paced nostalgic look at crime fighting in days when everyone wore a hat and called themselves Mr. & Miss.
