almost an old dark house movie . on the qualifying side and it a mystery and it have four murder and comic element and a very serious thunderstorm and stranded motorist and people hide in the shadow and and a big old dark boarding house . close enough and i would say and but i do not see any secret passageway and the film be make a bit late ( 1945 ) to qualify . good dialog and intelligently write for it type and and most ( but not all ) of the acting be competent . george zucco be especially good a the owner of the boarding house . 1940s frankenstein fan and and gunsmoke ( tv ) fan will greatly enjoy glenn strange comic role a zucco assistant while he funny and get to do a little slapstick . overall and quite an enjoyable film if you like this sort of thing ( i do ) . it hard to find this one and but it worth look for . i rate it positive .
