One of the better films in the Crime Doctor series, this entry has enough variety to sustain interest, enough characters to keep one confused, and enough twists and turns to keep the viewer guessing as to the perpetrator right up towards the end.
But where has the luscious Dusty Anderson, who plays one of the artist models, been all my viewing career? A bit player for Columbia around the end of WW II, research reveals that she married director Jean Negulesco and became a painter, not too far distant a profession from the one she plays in this movie. I'd suggest to anybody wanting to see more of her, however briefly, to look for her in one of several Rita Hayworth movies. (Check her IMDb.com entry for a list.)
For me, however, this movie was stolen by J. M. Kerrigan and Miles Mander, both of whom play art dealers, and both highly credible in their parts, the former a Scotsman who "would swim to Glasgow for a farthing" (if I recall the quote correctly), and the latter a sophisticated high-end dealer who doesn't sell any painting for under $500 (no small sum in those days).
