Whiz Tanner and the Vanishing Diamond

Whiz and Joey take a trip down memory lane when they try to get back into the magic business. Right away they are pulled back into detective mode–but it looks like magic has taken place. How could a diamond disappear without anyone near it? And this is only the beginning!
As they close in on solving the crime, it takes a drastic turn for the worse. Will the perpetrator figure out they know too much and try to eliminate the Tanner-Dent Detective Agency? They must take that chance and follow the clues to the end.

“A cozy, entertaining kids’ mystery. The finale offers a satisfying payoff.” -Kirkus Reviews
