Thank you for your wonderful review , and for reminding me that I need to revisit this great movie . The setting of Niagara Falls is an inspired choice for this noir . The acting is uniformly excellent throughout , and the film kept my interest from start to finish . This film is also a great reminder about how talented an actress Marilyn Monroe is . She was great in Don't Bother to Knock as well . I look forward to more of your entertaining and informative reviews , and I hope that all is well with you and your family . Thanks !
