“Tuesday!”

“Oh, puh-lease,” she muttered sarcastically, “are you really going to tell me you never showed your boobs to anyone at school for cash?”

“I might have,” I replied, “but that was completely different.”

“How was it completely different?”

“Mostly because Flossie Buxton dared me to. She was more into that sort of thing. Still is, actually. And . . .”

“And what?”

“I charged a pound.”

“Holy strumpets,” said Tuesday, making a quick mental calculation. “That’s the equivalent of—let’s see—over twenty-two pounds seventy-five pence in today’s money. Did you ever consider a career as a stripper? It was going pretty well for you.”

“No I didn’t, and yes, I know what we said, but please, no more flashing. It’s . . . undignified.”

I was actually relieved that she was taking the social side of being a sixteen-year-old seriously. She might be a supergenius, but we wanted her to be a real person, too—even if that meant her being a bit grumpy, sometimes uncommunicative and on occasion demonstrating ill judgment with boys.

“Okay, no more flashing,” she said.

“And especially not to Gavin Watkins.”

“I think he’s cute.”

“Cute? He’s a foulmouthed little creep.”

Tuesday giggled. She was pulling my leg. “No flashing, promise,” she said. “Boy, your face!”

“Very funny,” I said. “What are you doing to Pickers?”

I had turned my attention to her workbench, and in particular to our pet dodo, Pickwick, whom I had personally sequenced almost twenty-six years before, when the home-cloning fad was in full spate. She was a valuable V1.2—without wings, as all the early ones were—and unique in that she was not just the oldest dodo in existence but also sequenced before the mandatory autosenescence laws were brought in. Barring a major extinction event and the cat next door, she would outlive everything.

“Ah, yes,” said Tuesday, turning to stare at Pickwick, who was sitting patiently on the workbench. She was wearing a small, bronze domed cap on her head that was about the size of half a tennis ball, from which trailed a jumble of brightly colored wires.

“After rejiggling her DNA until her feathers grew back, I got to wondering in what other ways she might be improved.”

“I’m not sure Pickwick needs improving,” I said somewhat dubiously, since Pickwick had been with me for so long it was almost impossible to recall a time when she wasn’t wandering around the house, plocking randomly and bumping into furniture. “I’d miss her glorious pointlessness if it were taken away.”

“Okay, well, maybe,” said Tuesday, “but I found that reengineered dodo brains have neural pathways that are particularly easy to map. That copper helmet thingy she’s wearing is an avian encephalograph. By reading the electrical brain activity, I’m attempting to discover what’s going on in her head.”

“I’m not sure you’ll find very much,” I said, since despite my affection for the small bird, I was under no illusion about the level of her intelligence.

“In that you might be mistaken,” said Tuesday, “for with my newly invented Encephalovision I can decode and then visualize her brain patterns. Watch.”
