When you consider that sound had only come in a couple of years before THE BISHOP MURDER CASE, the fact that the film still has a soundtrack that needs restoration is no surprise. But I did manage to see a good print of the film on TCM and the gleaming B&W photography belied the fact that this was made in 1930.
But my sole purpose for watching was to see what BASIL RATHBONE looked like in an early detective role as Philo Vance. The mystery itself seemed a lot like an Agatha Christie whodunit because the murders were staged by a clever killer who just wasn't smart enough to outwit Philo Vance. The final revelation involves a glass of wine with poison in it ("the vessel with the pessel" film that Rathbone did with Danny Kaye comes to mind here). Rathbone's cleverness and manner of solving the crime is reminiscent of the way he played Sherlock Holmes so well in all those Sherlock films.
He also had a crisp delivery that was lacking in the other players. Only ROLAND YOUNG managed to sound as if silent films were a thing of the past. The others were clearly still in the silent mode of acting which makes Rathbone's performance even more remarkable.
Not a great mystery by any means and the sets, despite some fine photography, are on the primitive side--but addicts of detective stories should enjoy this one.
