Cast a Dark Shadow

After one year of marriage, fortune hunter Edward Bare, who is affectionately referred to as Teddy (as in "teddy bear") by his older, wealthy wife, Monica manages to kill her, making it look like an accidental death on her part, which it is eventually ruled as by the coroner. He killed her now as he recently had a discussion with her convincing her not to write a will, making him her sole beneficiary which she intended to do, as such casting any possible aspersion away from him as a murderer, under the presumption that she had no will, which would mean that her entire estate would go to him regardless. Edward is dismayed to learn that Monica did have a will written immediately after they got married, leaving all of her money to her Jamaica-residing sister, Dora, whom she had not seen in 20 years, but leaving him the house in which they live. Despite the will also stating that Monica's money would revert to him on the event of Dora's death, Edward has no means to be able to kill her. Monica's lawyer, Phillip Mortimer, makes it clear to Edward that he has never trusted him, and believes he is responsible for Monica's death. Within this context, Edward has no money now on which to live, making him move on to his next victim, brash Freda Jeffries, whom he meets at a seaside resort. Nouveau riche widowed Freda gained her wealth through the sale of her deceased husband's business, a saloon. Following Edward and Freda's marriage, he finds that Freda is not nearly as trusting of him with her money as Monica was with hers, Freda treating her money as her own, as such making Edward's task of living high off Freda's wealth more difficult. Freda's non-trust is due in part to Edward spending time with a woman named Charlotte Young, whom Edward, through his previous work as a property broker, is helping find some property to open an equestrian school. Edward knows that he can't kill Freda, at least not yet, because the death of two wives in such close succession would cause suspicion. However, Edward has no idea how profound an effect Charlotte will have on his life with Freda due to a secret Charlotte is keeping.
