Calm yer sen down. It has been noted that Sir Tom said his book publications were not to be involved in all the charity monies that were collected at the time. What his family have failed to do, was to inform anyone of this before his passing so now, questions are being asked by such as yourself.
I for one don't feel they have committed any crime and that they have only been foolish in not disclosing relevant information prior to Sir Tom's passing.
