A review from IMDb.com:

Once this gets moving, it's a good thriller with
an interesting story that is well worth watching.
It has a good cast, led by Basil Rathbone and Ann
Harding. The last half of it builds up the suspense
very nicely in leading up to a tense climax.

The story is a fairly straightforward one about
a young woman who is swept away by a charming man,
and then quickly marries him, but then begins to
wonder if he is really what he seems to be. The
first part is rather slow in setting everything
up (the Agatha Christie story on which the play
and movie are based is much more economical,
and just as suspenseful), but stick with it,
because the last part is more than worth waiting
for. It squeezes quite a bit out of the possibilities
that the situation offers, and you'll definitely
want to find out what happens. - Snow Leopard
