[shared copy] The Starbuck family is anything but ordinary. There are two sets of Starbuck twins: preteens Liberty and July, and their little sisters Charly and Molly. But even more extraordinary is the fact that all four children have the ability to teleflash―they can talk to each other without saying a word! It's a power that comes in handy whenever these adventurous kids are on the trail of a villian. When twins Liberty and July accompany their father on a business trip to London, a mysterious voice starts speaking through their teleflashing channels. Who is trying to contact them, and why ? Using the detective skills of their hero, Sherlock Holmes, the twins set out to solve a puzzle that takes them on an exciting journey through the streets of London.

The third-floor room was round like a castle turret, and a big old tree grew in the front yard, shading half the house. Liberty looked out through the tree’s inky green leaves at the peaceful morning. She could hear the creak of the porch swing, below, pushed by a whisper of wind. And that whisper—did it echo another whisper somewhere deep in her mind? Liberty ran her hands through her hair. She had been awake since sunrise, and it felt as if a voice in a dream had been speaking directly inside her brain—not a loud voice, just a whisper. But she could not remember the dream, and now even the whisper seemed to have vanished. Only a dim memory like an echo was left. She listened again, this time more attentively, to the wind pushing the swing. All of the other houses on this block where the Starbucks lived, in the northwest section of the city of Washington, D.C., were brick and had sharp corners. But the Starbuck house had two identical turrets, one cupola, very few sharp corners, and it was shingle, not brick. Despite the differences, Liberty thought, their home probably seemed as normal as the next. Given your average Martian— "Average Martian!" J.B. Starbuck burst through the connecting door to his twin sister’s room. "What is an average Martian, Liberty?" Liberty stared at her brother. His black hair slashed across his brow at the same steep angle as her own, except that his slashed right and hers slashed left. This morning his gray eyes were still foggy with sleep, while hers were clear and alert. She had been up for a half hour already. "J.B." was short for July Burton, and a lot of people called him by his initials. A select few called him "Jelly Bean." The twins had been born within five minutes of each other, during the first hour after midnight on the Fourth of July; that’s why their parents had named them July and Liberty. "Martians should not be your concern this morning, Liberty," J.B. said. "You mean Dad should?" He nodded. "I’m tired of Dad being our major concern. It’s getting boring, and"—she paused, her eyes worried—"it’s kind of scary." July knew what Liberty meant. It was scary. Things weren’t normal anymore, and at first that was fun—having their dad there when they got home from school every afternoon, going grocery shopping with him, having him help with their homework. But then it started getting a little frustrating. Their father had been out of work just a week when he first sat down with his laptop at the dining room table, where they always did their homework, and announced that he had some homework of his own—"world work," he had called it. That’s when he began doing Internet searches for all kinds of statistics about global warming. Indeed, within two days, their father knew so much about global warming that both twins decided to do a report on it for their civics class. They had a fight about that, however, when they realized they both couldn’t do the same thing. So their father obligingly found them a second environmental problem—acid rain—and began downloading information like crazy. Liberty, however, decided to do her report on the latest findings on twins that had been separated at birth, pairs that had grown up apart yet wound up drinking the same brand of beer, liking the same kinds of books, and wearing the same kinds of clothes. Sometimes when they married, they even gave their children the same names without ever knowing it! Liberty had always been very interested in the science of twins—the biology of twins, the psychology of twins, even the mythology of twins. "Twinology," as she called it, was one of her favorite areas of research. It was good to have their dad
