A tricky new murder case for the greatest detective duo since Holmes & Watson!
Christmas time in Vienna: for the two Master Sleuths, sled dog Athos and cat diva Pearl, it was supposed to be a relaxing vacation in the Austrian capital. But instead of getting comfortable in front of the fireplace and enjoying some delicious Christmas cookies, the two four-pawed detectives suddenly find themselves at the center of a murderous intrigue.
A respected university professor has been killed under mysterious circumstances. In the course of her research, she apparently made some very powerful enemies.
The trail leads the Master Sleuths to a place where death is omnipresent: Vienna's Central Cemetery. What do the silent stones and the whispering trees there have to hide?
