this be the first of three film that oliver and gleason make together a teacher miss withers and inspector piper . it be also the best and though murder on the blackboard be also top notch . the series continue without oliver and but not at the same level . the dialogue be witty and prim and sarcastic and sometimes even suggestive . gleason and oliver have a fabulous chemistry and the like of which would never be see today and due to cast decision that have more to do with pretty face that act talent and intelligence . if you like early talkie mystery and this one will satisfy anytime .
