There was nothing in James Throckmorton’s career to class him as a marked man. He had possessed wealth, but much of it had been expended in his hobbies.

He was a harmless person, whose chief weakness was ornithology. On various occasions, the members of the Falcon Society had visited his home.

These men were interested in the study of birds. It was mentioned, in the reports of the society, that Throckmorton had completed his book on ornithology a few months before. He had shown the manuscript to the members of the society at that time.
