Suddenly, and with a singular feeling of relief, I bethought myself of my old friend and fellow-student, John Thorndyke, now an eminent authority on Medical Jurisprudence. I had been associated with him temporarily in one case as his assistant, and had then been deeply impressed by his versatile learning, his acuteness and his marvellous resourcefulness. Thorndyke was a barrister in extensive practice, and so would be able to tell me at once what was my duty from a legal point of view; and, as he was also a doctor of medicine, he would understand the exigencies of medical practice. If I could find time to call at the Temple and lay the case before him, all my doubts and difficulties would be resolved.
