Thomas "T" Rex is a dinosaur super sleuth. He's kind of a loner, being top of the food chain and all, but he never eats his clients...well, mostly never. To be honest, he scares other dinosaurs, which works really well during his many investigations. Do you have a missing family member, or have you lost something important? Then, Thomas is your dinosaur. Alistair is an angry Ankylosaurus, and what brings him to Thomas's door is a deplorable robbery of ferns. Who would steal Alistair's favorite snack and, even worse, on his birthday? Thomas is hot on the trail, but there are so many sets of footprints at the crime scene! Will he ever figure out which herbivore is the culprit? Thomas, expert sleuth that he is, must solve this mystery in time to save poor, angry Alistair's birthday—or is something other than thievery going on here? With a focus on successive letters of the alphabet, the Dinosaur Detective series helps kids identify emotions, solve problems, and become familiar with letters of the alphabet. There are humorous asides for parents, too, as Thomas stomps his way to crime-fighting king.
