I'm trying to iron out the plot of a mystery, and I need to be clear on one basic thing before I go on. Here's the situation: there's been a murder, there's a suspect. Say that the suspect has inherited the victim's considerable property, victim & suspect were known to be on bad terms with each other, and there is no way to prove where they were at the time of the murder aside from their own testimony. Is this enough to have the suspect arrested for murder, or is more concrete evidence needed?
Oh, and this takes place around 1930, if it makes any difference.
