Payback. Harper Allen

made the Mafia look like pussycats. To complicate matters, he’d borne a grudge against her ever since she’d told him, in no uncertain terms, that she didn’t intend to date him until she had definite confirmation hell had frozen over.

      She’d returned the photo to him. “Go back to the computer and reconfigure this. No perm. My hair stays the length it is. I’ll go with a temporary rinse and wear it scraped into a bun while I’m undercover as Little Miss Repressed. When I walk out of here, I’ll be Dawn Swanson, right down to the baggy science-geek sweatshirt, but that persona’s not going to come from clothes or a hairstyle, it’s going to come from me. If you’ve got a problem with that, we’ll go talk to the big boss, as you refer to Dr. Peters, together.”

      She’d won that round, Dawn reflected now as she deliberately clashed the hatchback’s gears again. It hadn’t been until she’d reached the motel where she’d stayed last night and read the extensive bio prepared for her—a bio she’d later burned before flushing the charred scraps down the motel room’s toilet—that she’d realized Carter, with his own waspish sense of revenge, had gotten the last laugh.

      Swanson lives, breathes and sleeps fruit flies and genetics, the typed pages had informed her. Since seventy-two-year-old Sir William London is the world authority on her chosen passion, Swanson hero-worships him to the point of having a kind of crush on him. Several of the contacts we’ve blackmailed to supply references on our fictitious lab technician will mention the poster that supposedly hung above her bed at her college dorm—the famous shot of Sir William taken just before he won his first Nobel Prize in ’58, when he was one of Oxford’s “crazy young men.”

      In the margin, Carter had added a penciled note: Who knows, O’Shaughnessy, you might get lucky with the old geezer. Here’s hoping, girlfriend!

      “And here’s hoping that when the Cassandras and I take down Lab 33, you spend the rest of your sorry life behind bars,” Dawn muttered. She narrowed her gaze as the hatchback’s headlights cut through the desert blackness to illuminate an unmarked secondary road up ahead. Although the slight rises and dips in the terrain made it impossible to see what lay ahead, the road had to be the turnoff to London’s small but highly secure laboratory complex. She felt a surge of anticipation run through her. Since sound carried in arid terrain such as this, more so at night, her little maneuvers with the gears hadn’t been premature. They’d insured that any sentry with ears sharp enough to catch the first faint sounds of a vehicle approaching wouldn’t have heard Dawn O’Shaughnessy driving with her usual speed and skill, but Dawn Swanson, a woman who preferred to be surrounded by test tubes and petri dishes instead of behind the wheel of a car.

      Live the lie, Dawnie. Unbidden, the tobacco-roughened voice of Lee Craig broke through her concentration, so clearly that he might have been sitting beside her in the dark. That’s the first rule of deep cover. Forget who you are and become the identity you’ve taken on. It’s not always easy…but once in a while you might even find yourself wishing you didn’t have to go back to being the real you.

      This time when she geared down there was no pretence in her mishandling of the car’s controls. As she made the turnoff the hatchback veered dangerously close to the crumbling verge of the dirt road before she corrected its course.

      “Don’t worry, Lee,” she said savagely under her breath. “I’m living the lie, just like you did, you bastard. And like you, when my cover’s outlived its usefulness I won’t forget who I am and what my real agenda is. You took down my mother. I’m going to take out Aldrich—”

      Her words were cut off by a gasp and the hatchback swerved again. Her responses hampered by the intense pain behind her eyes, Dawn’s corrective maneuver came a split second too late. She felt the rear end of the car slide off the road, felt the back tires fight for purchase on the sandy soil, heard them churning uselessly as they merely dug themselves deeper.

      The hatchback stalled. The pain behind her eyes faded. Her hands gripped the steering wheel so tightly that her knuckles showed white in the greenish glow from the instrument panel.

      It was time to face facts, she thought numbly. Lab 33’s scientists might not know what the symptoms of her gene degeneration would be, but she couldn’t fool herself any longer. She’d never had a headache in her life before now, just as she’d never caught a cold or contracted the normal childhood bouts of measles and mumps and tonsillitis. So the migraines she’d been experiencing with increasing frequency over the past few months had to be a first warning signal of—

      Before her train of thought could reach its logical conclusion, she jerked open the driver’s side door and stepped swiftly from the car. Striding toward the back of the stalled vehicle, she planted her hands on her hips and glared at the deep depressions in the sand where the rear tires were now embedded.

      But standing still was a mistake. Unwillingly she found her mind completing the deduction she’d tried to thrust aside. If the loss of her invulnerability to common human ailments was the first symptom of her genetic breakdown, what else would be taken from her before she returned to Lab 33 with London’s research?

      In effect, your body will turn on itself. Peters’s words had filled her with dread at the time, but only now could she fully comprehend the horrific possibilities of his prediction. Her sight—would it slowly dim or would she suddenly be plunged into a world of darkness? Or maybe it would be her reflexes that would desert her at the very moment she needed them, or her hearing or her strength or—

      Her lips tightening, she bent to grab the rust-specked bumper of the hatchback. She took a deep breath and heaved.

      Even for her, it was a near-impossible effort. She felt the muscles in her arms scream in protest, felt her balance shift treacherously as the sandy soil beneath her feet crumbled. Sweat beading her brow and running down behind the heavy horn-rimmed glasses Carter had provided her with, she set her jaw in grim determination and began pivoting the rear of the car toward the road.

      There was a possibility that the security measures guarding Sir William London’s laboratory included roving teams patrolling past the fenced perimeter of the facility. If even one of those teams came upon her now, not only would her Dawn Swanson cover be blown, but the enhanced abilities she’d always been so careful about revealing would be immediately exposed. She was taking an insane chance.

      She didn’t care. All that was important right now was that she accomplish the superhuman task she’d set herself.

      “This is what you are.” The barely intelligible words came from her in a strained grunt as she took another trembling step sideways, the tendons in her shoulders feeling as though they were about to pop. “No matter what you told Peters, you’ll never be an ordinary woman—not like Kayla, with her unshakable integrity, or the rest of the Cassandras, who’ve found support in one another. Your strength and abilities may have come from a test tube, but they’re all you have. And when they’re gone…”

      Through the soles of her sneakers she felt the more stable surface of the road. Taking two last shuffling steps, she set the rear of the hatchback unceremoniously down onto its tires. Slowly she uncurled her grip from the bumper, her arms and back feeling as if they were on fire.

      She ignored the searing sensation and straightened to her full height. Behind the glasses her eyes squeezed tightly shut. “When the abilities are gone, what’s left?” she asked in an uneven whisper. “Face it, O’Shaughnessy, nothing…and that’s why you’re terrified for the first time in your life. Not because of the pain you’re going to suffer if this process isn’t reversed, not because you could die, but because before the end comes you’ll be revealed for what you are—a lab rat whose enhanced sight couldn’t help her see the truth, whose strength only masked the weakness that allowed Aldrich Peters to manipulate her for so long, whose regenerative powers couldn’t heal her destroyed soul. Any one of the Cassandras is more of a superwoman than you are. A mother working two shifts just to bring in enough money to keep her children fed is more of a superwoman than Dawn O’Shaughnessy ever was.”

      For a moment longer she stood there, her posture slightly bowed as if she were still carrying a crushing weight. Then she opened her
