Chronic Arsenic Poisoning

In the version that would tie into this, the kids are actually poisoned by the uncle with arsenic. You can have skin changes if you have chronic arsenic poisoning. And a lot of the pictures that i looked at looked a lot cause i've never seen a case of chronic arsenic poisoning in real life. Buti that change in pigmentation maybe gave their skins sort of a green cast or a green hue.
