The bats never left — and neither did the killer’s shadow. Step into mysteries that demand courage, discernment, and the will to seek the truth. Conceived and co-written by the daughter of Robert Arthur – the creator of the Three Investigators universe – this restoration of the classic series takes its iconic characters into a new age, with gripping contemporary adventures for young readers who crave meaning, want to share in the growth of characters they admire, and seek a world they can return to again and again. In the third book of a 26-book story arc, the Three Investigators head to Jackson, California, for a Fourth of July celebration at the vineyard of their new friend Branko Petrovic. Jupiter hopes the visit will bring him closer to solving the mystery of his long-dead mother, but his only clue is that she was Serbian - and her name, Amanda Morris, doesn't seem to fit. After receiving a finder's fee from their summer's first case, the boys use part of their earnings to buy a used car, and Worthington drives them north. On the way, Bob shares a story about André Laurent, a French-Canadian counterfeiter and murderer who had been arrested in Jackson twenty-five years earlier, only to skip bail and vanish. The investigation takes an unexpected turn when the boys stumble upon Laurent's old counterfeiting operation - an offset press and engraved plates for printing one-hundred-dollar bills - hidden deep in a cavern on Branko's family’s property, and guarded by a colony of nesting bats. But their interest and amazement soon turn to trepidation when they realize Laurent has returned to reclaim the stolen plates, and that they’re holding the evidence he'll stop at nothing to get back. Where has André Laurent been for the past twenty-five years and why has he burned off his own fingerprints? How does he find out where The Three Investigators are staying? And how is all of this connected to Jupiter's mysterious family tree? As fireworks light up the sky at Dragutin Wines, Jupiter uncovers part of the truth about his mother, but a dangerous confrontation with Laurent leaves him and his friends facing life-threatening peril. Join Jupiter, Pete, and Bob as they uncover the facts about a quarter-century-old crime, chase down a ruthless criminal, and discover the truth about Jupiter's parentage in this action-packed new addition to the Three Investigators series.
