stripped from a window; a metal box with dials and switches on it; a pair of long electrical wires; a roll of black tape; and an eight-inch sealed glass tube. He crouched at the sidewalk, where he deposited this load. 'I need your car,' he said to Littlemore, attaching the wires to the glass tube. 'How could I be such a fool?' 'Um - what are you doing?' said the detective. 'This is a radiation detector,' said Younger, connecting the other end of the wires to the metal box. 'Colette was going to use it at her lecture.'
'That's swell. Couple of things I could be taking care of right now, Doc.'
'Every sample in Colette's case is radioactive,' said Younger, connecting the other end of the wires to the metal box. 'Their car is leaving a trail of radioactive particles like bread crumbs. We can't see them. But this thing can - if we hurry.'
Younger flipped a switch on the box. A flash of yellow ignited in the glass tube, accompanied by an explosive blast of static from the box. Just as suddenly, the tube went dark and the box fell quiet. 'Was that supposed to happen?' asked Littlemore. 'Not exactly,' said Younger. 'Radioactivity should produce a blue current. I think.'
Younger picked up the box in one arm and extended the curtain rod out in front of him, with the glass tube taped to its end, as if it were the tip of a divining rod. Nothing happened. He stepped into Park Avenue, probing along the pavement and in the air. A single blue spark flashed inside the glass. 'Got them,' he said.
Younger took a step to his right. Nothing. He took a step the other way: another single blue flash lit the tube, and then another. He followed these sparks - until he was face-to-face with Littlemore, his wand pointing directly into the detective's chest.
'Hello?' said Littlemore.
'It must be because you got so close to the open case,' said Younger. He returned to the street, cars veering to avoid him. He was looking for a signal much stronger than the individual sparks that led him to Littlemore. In the middle of the avenue, a miniature blue firework burst within the glass tube. As he advanced down the avenue, the firework became a steady blue current, and audible clicks emanated from the metal box.
'Well, I'll be,' replied Littlemore for the second time that day.
Moments later they were driving down Park Avenue at full throttle, Littlemore behind the wheel, Younger standing on the running board. Younger held the curtain rod out in front of him, the glass tube at its tip sparkling electric blue in the warm Manhattan night.
In Times Square, the current went dead. 'They turned,' said Younger.
He jumped from the running board, carrying his apparatus, while Littlemore wheeled the car around. Younger searched for a signal. To the north, he found nothing. But when he went to the downtown side of the square, a blue current flickered back to life inside the glass. Soon they were heading south on Broadway. For more than two miles they hurtled down the avenue, the device flashing and clicking steadily.
'Why?' Younger shouted over the car's din.
Littlemore interpreted: 'Why kidnap her?'
Younger nodded.
'They take girls for two reasons,' shouted the detective. 'Money is one.'
What Colette would have done, had she been on her own, she didn't know. When the car finally came to a halt and they pulled her out into an unlit street, the two stupid underlings, Miljan and Zelko, fought with each other constantly. She might have made a run for it - if she had been on her own. But they had her brother too, so any thought of wrenching loose and running was out of the question.
Miljan - the small one, who smelled of onion - was apparently competing with Zelko to be keeper of their female prisoner. Each tried to yank her away from the other, coming to the point of blows until Drobac forced Miljan to take Luc, while
