The adventurer's season of prosperity was not long and by the end of 1890 he had lost the bigger portion of what the late Mr Dick Dunn used to call his "Sanfoinery." He recovered, however, over the Lincoln which was won by a horse called Lord George and also followed Colonel North's famous luck with much advantage to himself. At the close of 1891 it was rumoured that "the Prince" was about to marry into a family whose standing was high in Scotland. It was about this time, however, that Pinkerton began to make inquiries and the result was in every way detrimental to the "Prince's" plans for domestication. He was soon on the run and in 1893 was found trying to beat the Pari Mutuel at Longchamps, when the exclusion of bookmakers from the enclosures put a term to his turf activities. This man was by no means the most important of Lord Pinkerton's victims, for the vigilant peer's system of espionage was influential enough to close the doors of society to men whose wealth and influence in Africa was second only to that of Rhodes himself, but who failed to come up to our peer's ideas of what was morally fitting for the great London world of those days. Pinkerton's self-appointed rôle was not looked upon at all times with favour by the more liberal-minded members of what Thackeray calls the Best English People and, indeed, when one considers the origin of some of the so-called noble families of England, Ireland and Scotland, we think the social purist carried his apostolate just a little too far. Suicide was, in at least one case, the end of a victim whose social ostracism Pinkerton had brought about, and when several of his victims conspired to bring about a situation that publicly showed up the noble regenerator in a character which was at the very least embarrassing, and as a result of which much mud continued to adhere after the disposal of the case in a magistrate's court, very few people were found to sympathise with the only social spy whom our peerage has probably ever produced.
