'40s Murder Mystery Movie [SOLVED!]

Thanks, Nusyrinx!

I just pulled it up and don't think that's the one, but it's that kind of feel, absolutely.

P.S. There's definitely something about a lake in the end, if I'm remembering correctly. 

Hi Takeshi--

Thanks for your suggestions!

Yes, I saw that One Thrilling Night has a few titles, and I also watched the first few minutes of the movie from the Wikipedia page (at the bottom there's a link), and that's not it.

As for Nick and Nora--I'm a huge fan of the Thin Man series, and I'm certain that that's not it either. But it seems like the sort of thing that was inspired by the Thin Man--not Star of Midnight, The Ex-Mrs. Bradford, or Remember Last Night?, all of which were more-or-less imitations (well, in the last case more a parody of the original) and early '30s, but my movie seemed more '40s, screwball, something like that. 

Thanks again!

I guess I'll be rude (sorry!) and bump this one as well. Any connoisseurs of '30s-'40s movies who happen to know a movie with this description? Probably (if it helps!) based on a book by one of the mystery authors of the period, just as Mr. and Mrs. North was based on a series by Richard and Frances Lockridge.

That's what I wanted to do, Carl, but then I didn't know how everybody would take it, seeing how there is this "I Need to Know" board here already. But, if you think it will be all right, I can post it there too. Thanks!

OK, swell, Carl. I just posted it there.

Thanks for your interest, Taranthian! 

As for your questions...

I'm not certain that it was American; it might have been British. I would lean towards its being an American picture, just because it seemed like a Thin Man knock-off of the American "screwball" variety, but I can't be absolutely sure. Either way, it was definitely in English. 

I don't know if the team were regular or a one-off, unfortunately. Probably a one-off, because I've never seen it mentioned on any list? 

I can't remember any famous names; it was definitely B&W.

I don't know about its length, but these kinds of movies, whodunits, tended to be on the shorter side.

Sorry I don't know more, but hope that helps. Thanks again!

Thanks! 

I have a distinct memory about a lake, by the way. I'm positive on that: the hotel's probably near the lake, then. 

Could be, Tarathian, but '40s is what popped into my mind immediately, if I remember it correctly. You know how sometimes you can just tell the era a movie was from? But, I mean, I suppose it could be late '30s or early '50s.

Very funny! I just recommended that one (which I haven't seen) to another poster on a different forum. How's that for a coincidence? 

Unfortunately, that's not the one, as you thought, but thanks. "Mine" was not a noir at all--on the contrary, it was very light and funny, as befits a movie that probably was cashing in on the Thin Man craze! 

Speaking of The Thin Man... Wait a sec. I'm thinking there might have been a scene in my movie involving a bar. The couple were sitting at a bar with another character, and the bartender was growing angry because they were drinking so much, or... Nope, just lost the memory. But maybe something like that? 

And, at the end, the murderer, who had been friendly the whole time, takes the husband away to some secluded location near the lake--a lake house, maybe?--and that's where he stuffs him in the trunk. I think.
