The thesis he put together in his book was that lead poisoning in the canned food probably caused the demise of the expedition, ... But looking at that thesis, it didn't seem to hold water, so I decided to go looking around for a more plausible explanation for what might have killed off the expedition. |

We're talking an extremely potent poison which, even in minute quantities, is deadly and usually does kill in 48 to 72 hours. So my thesis of the book is that is indeed what happened to them. |
