"Ah, such ignorance. But then, you don't wander much in feminine society, do you? Mrs. Bruce told me about it this morning. Chain Lightning's Collar."

"Chain Lightning's what?"

"Ah, my boy—" Mr. Paddock lighted a cigarette. "You should go round more in royal circles. List, commoner, while I relate. It seems that the Earl of Raybrook is a giddy old sport with a gambling streak a yard wide. In his young days he loved the Lady Evelyn Hollowway. Lady Evelyn had a horse entered in a derby about that time—name, Chain Lightning. And the Earl of Raybrook wagered a diamond necklace against a kiss that Chain Lightning would lose."

"Wasn't that giving big odds?" inquired Minot.

"Not if you believe the stories of Lady Evelyn's beauty. Well, it happened before Tammany politicians began avenging Ireland on Derby Day. Chain Lightning won. And the earl came across with the necklace. Afterward he married Lady Evelyn—"

"To get back the necklace?"

"Cynic. And being a rather racy old boy, he referred to the necklace thereafter as Chain Lightning's Collar. It got to be pretty well known in England by that name. I believe it is considered a rather neat piece of jewelry among the English nobility—whose sparklers aren't what they were before the steel business in Pittsburgh turned out a good thing."

"Chain Lightning's Collar," mused Minot. "I presume Lady Evelyn was the mother of the present Lord Harrowby?"

"So 'tis rumored," smiled Paddock. "Though I take it his lordship favors his father in looks."

They walked along for a moment in silence. The story of this necklace of diamonds could bring but one thing to Minot's thoughts—Martin Wall drooping on the steps of the Manhattan Club while old Stacy roared with joy. He considered. Should he tell Mr. Paddock? No, he decided he would wait.
