Macnevin published his 'Pieces of Irish History'[181] at New York in 1807, and notices the betrayal of the memorial which he had addressed to the French Government. Up to that time, and until his death in 1840, he does not seem to suspect Turner. Had any such doubt occurred to him, he would have been the first to avow it. At p. 146 of his book Macnevin inveighs against a 'profligate informer,' 'a ruffian of the name of Reynolds;' but Reynolds' treachery was confined to the arrests at Bond's in Dublin, and did not take place until March 1798. Ten pages further on Macnevin speaks of the 'unparalleled fidelity of the United Irish Body.' Dr. Macnevin was struck by the knowledge the Government had acquired of the 'negotiations of the United Irishmen with foreign States,' and, he adds, 'at this time one of the deputies [_i.e._ himself] had personal evidence of its extent and accuracy. That knowledge was obtained from some person in the pay of England and in the confidence of France.' And Dr. Macnevin then proceeds to point to REINHARD by name! This is just what the officials of the Home Office wished for all along. Wickham, referring to the publication of Macnevin's memorial by the Secret Committee of the House of Lords, writes: 'It may fairly be presumed that the copy has been obtained at [the Foreign Office] Paris, or from R.'s [Reinhard's] secretary at Hamburg. _This conjecture will be at least as probable as the real one._'[182] One circumstance struck Macnevin as 'confirmation strong' of his dark suspicion. Reinhard, as he tells us, made difficulties about giving him a passport to Paris. A most important despatch from Reinhard to De la Croix thus concludes:-- What I must particularly urge, Citizen Minister, in regard to this business, is, at least, that you will have the goodness to direct me as to Mr. Macnevin. I will not give another passport without your order.[183] This letter--possibly written at Lady Edward Fitzgerald's house at Hamburg, and put into her post-bag--was treacherously betrayed to Pitt. When De la Croix remained ominously silent in response to the above appeal, is it surprising that Reinhard should have made difficulties and delays in giving Macnevin a passport?[184] Macnevin's groundless distrust of Reinhard naturally influenced the views of a most painstaking investigator. Dr. Madden, who, when he at last saw, in the 'Castlereagh Papers,' Reinhard's letters to De la Croix, regarded the circumstance as damning proof of his treachery.[185] Subsequently Mignet, the great French historian and keeper of the ministerial archives at Paris, who had ample official means of knowing the character and acts of both Reinhard and De la Croix, assured Madden in writing that both men were incorruptible. This may be taken as conclusive, for, unlike Turner, there is not a line in any English State Paper tending to compromise Reinhard or De la Croix.[186]
