Note: this book contains neither crosswords nor ciphers in the traditional sense! The Notorious NBG head to Peru to help their temporary bud Carla, who is taking a secretarial course despite being ridiculously wealthy. She has a 300-ish year old family heirloom that only a white teen lady detective can decode! Ned cameos as her concerned beau who takes her on a romantic trip to the hotel airport. The girls hit up several world heritage sites, which are just wantonly defaced, and L. Ron’s newest recruit lobs an ACTUAL BOMB at our heroes. It’s a wild (colonial) ride! No mummies we’re (probably) harmed in the making of this outing.
