A fun night out at a lively music concert takes a painful turn when Dink accidentally injures his arm and ends up needing a heavy plaster cast. But a broken arm is just the start of the trouble for the young detectives. While the kids are enjoying the concert, the famous singer's dazzling, expensive diamond necklace vanishes into thin air. At first, the two unfortunate events seem completely unrelated to each other. Then, Dink, Josh, and Ruth Rose slowly realize that Dink's hospital x-ray might actually hold the invisible secret to the entire crime. Put on your detective hat and join the trio as they closely examine the medical clues to track down the missing jewels. You will have to connect the hidden dots and look far beyond the obvious evidence to catch a very clever, fast-moving jewel thief. The answer is right there in black and white, waiting for you to find it.
