The Monthly Film Bulletin wrote: "Comedy thriller in which sliding panels, priest-holes, ex-convicts and priceless jewels are used to conventional effect."
Kine Weekly wrote: "Most of its trappings are borrowed from the stage but thanks to brisk team work, resourced direction and authentic atmosphere, new laughs and fresh excitement are worked in the old malarky. Good, clean fun as well as a lively thriller."
Picture Show wrote: "A comedy melodrama which has the usual ingredients of a thriller but moves at a quick pace. ... Well staged and directed, the laughs alternate with the thrills."
The Radio Times Guide to Films gave the film 2/5 stars, writing: "this is Hammer hokum of the hoariest kind. There isn't a semblance of suspense ... Not even the arrival of jewel thieves at the haunted house ... can revive one's fast-fading interest. However, there is one good wheeze, during the credit sequence, when director Francis Searle reveals that the front of the old house is merely a flat piece of scenery erected in a field."
Fantastic Movie Musings & Ramblings concluded, "it isn't much of a movie, but if you take it for what it is (a late-period old dark house variant based on a stage play), it has its uses. There are a few mildly amusing jokes and a couple of decent plot twists, which is more than some examples of this genre have." ==References==
