"Simple. Just don't let on anything's wrong. Pretend that the wedding's to come off as scheduled. Then tell him that things are in a mess. All the excitement's got you tied in a knot. Because he's such a close friend of Elaine's, you thought maybe he'd be willing to lend a hand."

The spark of hope in the professor's eyes brightened to a glowing coal.

"I wonder...." he mused. "It might work—"

"Of course it'll work. It's got to. It's the only chance we have...."

It was nine fifteen precisely when Adrian Vance rang the doorbell. He stepped back. Polished the nails of his right hand on the grey suede glove which still garbed the left.

The door swung open.

"Good morning, professor."

"Good morning, Adrian." The savant stepped aside. "Please come in."

Not by the slightest vocal tremor or change of expression did the old man hint of his secret—that if necessary Adrian Vance would never leave this place alive!

"It is kind of you to come," he told the antiquarian as he led the way toward the back of the dwelling. "I never knew that a wedding could cause so much turmoil." He chuckled softly. "Of course, I have had little experience in such matters, my wife being dead and Elaine an only child. And my own nuptials were celebrated a good many years ago."
