I think what can be seen behind is a draft version which has been inked over. The first one is clearly Lodging House Keeper, like the even clearer darker one.
Rather sneakily, they've changed the order of the words for the cause of death, but that does actually help a bit. The faint version ends with 'Complaint', and the dark one ends with 'of the Heart'. Put them together, and you can make it out as 'Complaint of the Heart' (dark) or 'Heart Complaint' (faint).
(Exactly which complaint of the heart may be forever a mystery.)
