Books in the A&a Detective Agency series

Follow clues, solve puzzles, crack the code . . . find the missing millionaire. When Dr. Alistair Fairfleet, the Fairfleet Institute's eccentric chairman, disappears on the first day of Alex Foster and Asha Singh's summer vacation, they receive a letter inviting them to a game involving complicated clues and puzzles. It is just the sort of case they've been waiting for. But nothing in the Fairfleet case has a simple solution. As the kids track down clues, they uncover art forgeries, archaeological crimes, and Fairfleet family secrets that will test their partnership and force them to confront the complicated legacies of the people and places they admire most.
