"I met Voivode Dracula in 1892 in Romania," Holmes is almost chatty. "We spent a most convivial evening in conversation. I would have gladly remained to peruse his library, but I had pressing business. More recently, here in Margate, I met a most delightful young lady, Signorina Isabel Giovanni. I was going to do some research for her."
Holmes listens gravely, his cigarette burning unheeded. "I congratulate you." He bows his head respectfully. "It cannot have been an easy task."
