Books with title The Great Mogul Diamond by Taylor, G. P.

Everything was going so well for a change. Sadie and Saskia Dopple, those troublesome twins, had been adopted by the wealthy writer and recluse Muzz Elliott. And their friend Erik Morrissey Ganger was finally on his way to becoming a full-fledged private detective. But when an anonymous note threatens someone they love, the twins are off on an express train to danger. Suddenly they find themselves awhirl in a series of crimes―stolen right off the pages of Muzz Elliott’s own mystery novels. The twins need to figure out who’s behind this twisted plot soon, or Muzz Elliott will be framed for her own greatest literary invention . . . the theft of the Great Mogul Diamond. Meanwhile, Erik speeds through the countryside in an unbelievably cool car with private eye Dorcas Potts, racing the clock and attempting to outwit a gang of robbers. At the end of the road (if he ever gets there), he and the twins will have to get their hands on the diamond first in order to save Muzz Elliott. But not even this car is fast enough to escape the nagging doubts in Erik’s mind . . . What do you do when you aren’t sure what’s right? Sadie, Saskia, and Erik face this question head-on in the third installment of The Dopple Ganger Chronicles, by New York Times bestselling author G. P. Taylor.
