El servicio secreto

Good WWII concept for a mystery story and the script is not bad except for a bit of routine mystery-movie padding typical of the era. This film is crisply and professionally edited, better than most low-budget films. And there are a few surprisingly good cinematography highlights.

The discount supporting cast does a good job although you may not recognize some of them, and you will notice that Sarah Edwards develops a watchable odd character who has custody of all the keys to the house. Mantan Morland has some poorly written throw-away dialog but his comedy timing is perfection and his performance is very polished as he does a great job.

Sidney Toler gives us a first rate Charlie Chan. The remarkable 70-year old is vigorous, keeping the proceedings moving as he strides briskly and confidently through all the scenes.

Moves at a good pace and held my attention throughout. What more can you ask for in a murder mystery?
