The Sherlock Files Series

Xander’s classmate gives a report at school about a famous amulet of the Egyptian god of time, Thoth. It was thought to be so powerful that it could turn back time one day every hundred years. And that day will come in a week!
The amulet disappeared from a museum in London years ago. Xena and Xander’s celebrated ancestor, Sherlock Holmes, tried to find it, but with no luck. The twins are on the case—but so are some mysterious foes who are trying to thwart and perhaps even harm them! Can Xander and Xena track down what Sherlock Holmes could not?

Xena and Xander Holmes are back . . . and so is a mysterious beast from Sherlock’s casebook!

Xena and Xander have been looking forward to their vacation in the peaceful country village of Blackslope. But when a huge monster begins to terrorize the town, the young detectives are faced with a mystery that seems impossible to solve. 
           
Sherlock Holmes, Xena and Xander’s famous ancestor, investigated the case of a horrible beast in Blackslope, but that was nearly a hundred years ago. It couldn’t be the same creature after all this time—or could it?

Go to The Dancing Men and ask for a saucer of milk for your snake. Then all will be revealed.
