For the resourceful, patient, mystery-minded sleuth wanna be in your life, these three interactive books can be mixed and matched as suites their taste. I know an otherwise upright, honest 60-year-old woman who would lift The Crimes of Dr. Watson from my shelf, squirrel it away to her lair, then ponder its pages, notebook in hand, from the privacy of her reading chair—if she thought I wouldn’t notice it had gone missing. Then next visit, she might eye the Batman and Dracula versions which may not be her first inclination but they just might quench, at least for a time, her insatiable love of mysteries. We all know how close the law abider and the lawbreaker are to one another. In the spirit of Christmas, I’m going to spare my friend any criminal charges, and make all three a gift for her. You might do well to follow my example.
