The Shirley Link Box Set

*The author is listed as Ben Graham at Amazon, but shows under Ben Zackheim's profile. Ben Graham doesn't have one. I have listed both authors here. Shirley Link & The Safe Case Someone stole thirty thousand dollars, which is bad enough. But the thief also took the one-ton safe that stored the cash! How is that even possible? Shirley and friends need to find out if they want to save their favorite school principal from getting axed. Shirley Link & The Hot Comic Someone is after a mint copy of The Avengers #1, worth over $100k. He's taunting the police with notes about when he'll pull off the heist. Whoever is behind the notes also wants to pull Shirley into a battle of the brains. Can she outwit a brilliant, determined criminal and save Thor, Hulk and Iron Man from his nefarious plot? Shirley Link & The Treasure Chest Shirley proves how rewarding it is to get out of the house and explore. During a casual stroll through her town's sewers (don't ask) she stumbles on evidence that Shelburne Falls' underground is hiding something. But what? As she digs deeper she finds evidence that a pirate's treasure is waiting to be found. Can she work through the clues and unearth the fortune?
