Plot hole: Enola and Tewkesbury make an unpremeditated decision to visit the Basilwether estate. This decision was made on the spur of the moment, and no-one knew about it. but when they arrive, Linthorn, who is supposed to be in London looking for Tewkesbury, is waiting in ambush to kill them. (01:32:45 - 01:34:31)
Suggested correction: Linthorn saw them in London. He travelled back to the Basilweather estate, and waited for them to slowly make their way there.
Enola and the young Tewkesbury were in London two weeks prior to Enola's forced enrollment in a boarding school where she was supposed to spend her next few years! Furthermore, there is no evidence of Linthorn having seen them.
Plot hole: The girl disappeared from the RV. The RV is a crime scene - it should have been taped off, finger printed, and searched for trace evidence with luminol and a forensic light source. There is no crime scene (forensic) unit present on the scene. However, the parents are sitting in the RV waiting for the cops to contact them about their missing child. (00:19:00 - 00:20:00)
