The Secret Mummy: Book 4 (Mortensen's Escapades) [Idioma Inglés] - Tapa blanda

"Time agent Mortensen has another odd mystery on his hands--what do Romanian vampires in 1891, a tourist in Prague in 1993 who vanishes and reappears minus a kidney, and an antiques auction in Paris in 1954 have in common? Those seemingly disparate things eventually come together in this fourth volume of the Mortensen's Escapades series, which compensates for a sometimes-thin plot with exciting and age-appropriate art. Research notes at the end help tie together the time-travel-meets-urban-legends story." --Booklist

In the sleepy village of Brasov, nestled in a region of Romania better known as Transylvania, seven villagers have been found with fang marks on their necks. Mortensen isn't the superstitious sort, but he heads back to 1891 to find some answers. A trail of stolen antiques, including a priceless mummy sarcophagus, leads him a hundred years later to Prague where a young tourist has suffered a similar attack. This looks like the work of a time-traveling vampire! And Mortensen thinks he's out for more than just blood.
