The information currently provided by the Nelson family primarily consists of a series of agricultural documents. Evidently, the Nelson family had once attempted to manage this manor throughout history, but for various reasons, ultimately failed to meet their objective.
Despite Nelson's family's failure to achieve their goal of managing the manor, these documents were still saved, even though the manor was mostly donated to the state to become a nature reserve, as a way to avoid huge property taxes.
These documents are of utmost importance to Leonard, as the documents they have previously acquired explicitly mentioned that the contents of the fifty wooden barrels were stored in the wine cellar, which cannot be dug just anywhere.
Considering that this place is in England and not in Scotland, the wine cellar referred to here is actually a cellar for storing wine, and such a facility is obviously not a problem that can be solved by just digging a hole.
