The answer to these questions is given in the theory adopted by the officers of the law immediately upon the discovery of the body; which was subsequently endorsed by the coroner's jury, re-indorsed by the Grand jury; and in pursuance of which seven men were soon to be placed upon trial for actual participation or complicity in the crime. This theory was that the physician had fallen a victim of a conspiracy, covering two continents, its ramifications extending in numerous directions and involving people of high as well as low repute, and that this conspiracy had for its object his deliberate removal in order that certain secrets and information that he possessed, and which virtually affected the reputation, honor, and credit of certain Irishmen of international reputation, might not be given to the world. In order, however, that this theory may be made clear, it is necessary to go back to the beginning of the trouble. Almost from his boyhood days Dr. Cronin had taken an active interest in organizations that had for their object the liberation of Ireland from British domination. One of these organizations was the Clan-na-Gael. This was probably the most closely oath-bound of all the Irish Societies of this country or abroad. Its strength, moreover, was phenomenal. Although, owing to the secrecy which surrounded its annual conventions, no public reports of its total membership had ever appeared of record, it was generally believed and understood that it ran into many scores of thousands, and penetrated into almost, if not quite, every section of the North American continent. In age it dated back to 1869, its cardinal object being to establish in Ireland an Irish republic, to bring about fraternal feelings among Irishmen in the United States, and generally assist in the elevation of the Irish race. It affiliated with the old revolutionary organizations in Ireland, and moved on lines so nearly masonic in their secrecy, that in many parts of the country the clergy of the Catholic church either discouraged or altogether forbade the members of their flocks from becoming identified with it. Despite this fact, however, the order, almost from its inception, grew in strength, in wealth, and in influence. There was nothing in the obligation which would-be members were compelled to take, before being entrusted with the pass-words and other secret work that conflicted with their duties as citizens of the United States, except that the occasion might arise when it would be necessary for them to violate the neutrality laws. Every man, however, that joined the Clan-na-Gael, or, as it was more generally known to the outside world, the "United Brotherhood," knew that, as an Irishman or a man of Irish descent, his sworn duty was loyalty to Ireland, and that, were he called upon to take up arms in aid of any movement for the independence of Erin's Isle, it would be his duty to comply without question or demur. The membership of the organization was
