This theory is borne out by the fact that on the day Morgan was taken to Canandaigua several prominent men of Batavia called upon Mrs.Morgan and told her that if she would give up to the Masons the papers she had in her possession Morgan would be brought back.

She gave up all the papers she could find; they were submitted to Johns, the former partner of Miller, who said that part of the manuscript was not there.

However, the men took Mrs.Morgan to Canandaigua, stopping at Avon over night.

These men expected to find Morgan still in Canandaigua, but were surprised to learn that he had been taken away the night before, whereupon Mrs.Morgan, having left her two small children at home, returned as quickly as possible.
So far as Morgan's manuscript is concerned, it seems that a portion of it was already in the hands of Miller, and another portion secreted inside of a bed at the time he was arrested, so that not long after his disappearance what purports to be his book was published.
Nearly two years later, in August, 1828, three men were tried for conspiracy to kidnap and carry away Morgan.

At that time it was believed by many that Morgan was either simply detained abroad or in hiding, although it was strenuously insisted by others that he had been killed.
