The wise-cracking Leslie Fenton (as "Barry") sounds quite a bit like James Cagney in his gangster days. The lovely Muriel Evans (as "Julie") looks quite a bit like Jean Harlow. The movie is not a true "Old Dark House" movie, because it doesn't have some of the elements required to qualify, but there is an old dark house, a hidden treasure, & lots of mystery. "House of Secrets" is interesting, the dialog is snappy with lots of current day (copyright 1936) slang, the acting is good, the sets are dark & spooky, & there are a few neat sub-plots (one involving Chicago mobsters). What drags this movie down a bit is the redundancy. I couldn't count the number of times Barry asks "What's going on?" & Julie (among many others) replies "I can't tell you." Although I was eventually able to guess the ending, it was difficult to figure out, & fun meanwhile. I rate it 6/10.
