Get ready for round-the-world adventure with Sam Spinner and her brother Nipper in the first book in a new hilarious, puzzle-packed series filled with super-secret messages! Perfect for fans of Escape From Mr. Lemoncello's Library and classics like Holes. Samantha Spinner's uncle Paul disappeared, and here's what he left: * Samantha's sister got a check for $2,400,000,000. * Samantha's brother got the New York Yankees. * And Samantha got a rusty red umbrella with a tag hanging off its worn handle. The tag says "Watch out for the RAIN." Thanks a lot, Uncle Paul. After all the strawberry waffles, stories, and puzzles they've shared, how could he just leave without saying goodbye? And what is the meaning of that mysterious message? The answer is simple. Sam knows in her heart that Uncle Paul is in danger. And if he taught her anything, it's that not everything is exactly what it seems. Which is why we should pay close attention to that rusty red umbrella, and never trust a monkey at a hula-hoop contest. The RAIN is coming and Samantha Spinner is about to find herself mixed up in some super-important, super-dangerous, super-secret plans.

X is the New York Times number 1 bestseller and thrilling, twenty-fourth book in the Kinsey Millhone Alphabet series from Sue Grafton. In hindsight, I marvel at how clueless I was . . . What I ask myself even now is whether I should have picked up the truth any faster than I did, which is to say not fast enough . . . When a glamorous red head wishes to locate the son she put up for adoption thirty-two years ago, it seems like an easy two hundred bucks for private investigator Kinsey Millhone. But when a cop tells her she was paid with marked bills, and Kinsey's client is nowhere to be found, it becomes apparent this mystery woman has something to hide. Riled, Kinsey won't stop until she's found out who fooled her and why. Meanwhile, the widow of the recently murdered P. I. – and Kinsey's old friend – Pete Wolinsky, needs help with her IRS audit. This seemingly innocuous task takes a treacherous turn when Kinsey finds a coded list amongst her friend's files. It soon leads her to an unhinged man with a catalogue of ruined lives left in his wake. And despite the devastation, there isn't a single conviction to his name. It seems this sociopath knows exactly how to cause chaos without leaving a trace. As Kinsey delves deeper into the investigation she quickly becomes the next target of this tormentor. But can Kinsey prove her case against him before she becomes the next victim?
