I had come across Lord Vaughn in a number of highly suspicious circumstances. His name kept popping up in the annals of the Pink Carnation. Wherever he appeared, he brought with him death, destruction, and a devastating way with a quizzing glass.

The first time Vaughn's name had intruded upon my notes, it was in connection with the death of an operative of the War Office, who had been placed in Vaughn's household as a footman. No one ever really explained that one. The assumption was that the footman had been murdered by the Marquise de Montval, the deadly French operative who worked for the even deadlier Black Tulip (and by the time you've gotten to two levels of deadly, you're talking pretty deadly).

Did I mention that the Marquise had been Vaughn's mistress? The association might have been purely amorous — or it might not have been. It was Vaughn who had released the Marquise from the custody of the English War Office, and Vaughn in whose company she had traveled to Ireland to foment rebellion on behalf of France. In short, Vaughn was looking pretty darn suspect. Add to that a decidedly sinister manner of dress, an extended stay on the Continent, and rather flippant ideas about the value of King and country, and you had a likely candidate for Traitor of the Year.

I had been thrilled when I discovered that the choice art museum, the Vaughn Collection, had belonged to that Vaughn. I'd heard of the Vaughn Collection — it had been prominently featured in my guidebook as a must-see for the serious student of art along with the Wallace Collection and the Sir John Soane's Museum — but it took a while for the connection to click. Vaughn, after all, was a fairly common name.
