Maybe if we asked Vic, he might be able to look in to the matter. he might not... but it's worth a try.
Vic are you able to help with the following:
Was the bloodstained bible returned to the relatives?
Have any relatives made the same connection as Caroline, regarding the nature/source of the stain, i.e. partial palm print?
If so, how do the relatives see this as fitting in to the sequence of events?
What is the opinion of the relatives in relation to how the partial palm print seems to knit with the finger-like marks on the nightdress?
