The plot of Alias Betty (2001) is a bit too good for most screenwriters to have concocted, but not too good for the novelist Ruth Rendell, on whose novel–The Tree of Hands–it is based. A French film by Claude Miller, it concerns a mentally unbalanced woman who kidnaps a little boy in order to make a gift of him to her grieving, now childless grown daughter. What we have here is a person whose suffering drives her to become comfortable with an immoral situation. Several story strands are juggled perfectly; the novel is adroitly adapted. Nothing wrong with the acting either.
