I almost died when Valmont's radio crackled again and Marcone's voice said, "There. As agreed, plus your additional fee. Will that be sufficient?"

"Quite. You will find your merchandise in a storage closet in the basement."

Marcone's voice gained an edge. "Please be more specific."

I slipped out of the vents, thinking silent thoughts. A long stretch put my fingertips on the tube's carrying strap.

"If you wish," Valmont replied. "The article is in a locked room, in a courier's tube. The tube itself is outfitted with an incendiary. A radio transmitter in my possession has the capacity to disarm or to trigger the device. Once I am safely on my way from the city, I will disarm the device and notify you via telephone. Until that time, I suggest you do not try to open it."

I jerked my fingers away from the tube.

"Again you have altered our agreement," Marcone said. He said it in a voice as smooth and cold as the inside wall of a refrigerator.

"It does seem to be a seller's market."

"There are very few people able to speak about taking advantage of me."

Valmont let out a quiet, bitter little laugh. "Come, now. This is nothing more than an entirely reasonable piece of insurance," Valmont said. "Be a good boy and your precious cloth is in no danger. Attempt to betray me, and you'll have nothing."

"And if the authorities find you on their own?" Marcone asked.

"You'll need a broom and a dustpan when you come for the article. I should think you would be wise to do whatever you can to clear the path for me." She turned the radio off.

I bit my lip, thinking furiously. Even if I took the Shroud now, Marcone would be upset when he didn't get his hands on it. If he didn't have Valmont killed, he'd at least tip off the police to her. Valmont, in turn, would destroy the Shroud. If I took it, I would have to move fast to get the Shroud away from the device. I couldn't count on simply blowing the device out with magic. It was as likely to malfunction and explode as it was to just go dead.

I would need the transmitter too, and there was only one way to get it.

I stepped up behind Valmont and pressed the bill of the plastic duck against her spine. "Don't move," I said. "I'll shoot."

She stiffened. " Dresden ?"

"Let me see your hands," I said. She held them up, the green light of the palmtop showing columns of numbers. "Where's the transmitter?"

"What transmitter?"

I pushed the duck against her a little harder. "I've had a long day too, Miss Valmont. The one you just told Marcone about."

She let out a small sound of discomfort. "If you take it, Marcone will kill me."

"Yeah, he takes his image seriously. You'd be smart to come with me and get protection from the authorities. Now where is the transmitter?"
