Three days after the explosion, the “Daily Record,” which had from the first given exceptional prominence to everything connected with the outrages, issued a special supplement, in which, in a letter to the people of England, the editor said that in view of the infamous conspiracy which had been formed against the welfare of the British Empire, and against the lives of British citizens, the proprietors of the “Daily Record” had some months ago decided to bring all their resources, capital, and energy to bear upon the discovery of the promoters of the conspiracy. In the carrying out of this investigation, the services of the very ablest English and foreign detectives had been engaged, their instructions being that, so long as absolute secrecy was observed and ultimate success attained, the question of expense was to remain entirely unconsidered. As a result, he was now able to supply the names and, in three cases, personal descriptions and portraits of seven men who were beyond all question the leaders of the movement, and one of whom--though which he regretted he was at present unable to say--the notorious Captain Shannon himself. The proprietors of the “Record” had not intended, he said, to make known their discoveries until the investigation had reached a more forward and satisfactory stage, but in view of what had recently occurred they had decided that it would not be right to withhold any information which might assist in bringing the perpetrators of the diabolical outrage to justice. In conclusion, he announced that the proprietors of the “Daily Record” were prepared to offer the following rewards:-- First, they would pay to any person, by means of whose information the capture had been effected, a reward of £3,000 per head for the arrest of any of the seven men whose names appeared on the list. Secondly, to any person who would give such information as would lead to the arrest of Captain Shannon, and at the same time furnish proof of his identity, they would pay a reward of £20,000. And in offering these rewards they made no exception in regard to the persons who were eligible to claim them. So long as the person claiming the reward or rewards had supplied the information which led to the arrest or arrests of the individuals indicated, the money should be faithfully paid without question or reservation. Needless to say the publication of this letter, with the names, and in three cases with portraits, of the men who were asserted to be the leaders of the conspiracy, and the offer of such large rewards, created a profound sensation not only in England and Ireland, but in America and on the Continent.
