Whiz Tanner and the Vanishing Diamond

Whiz and Joey take a trip down memory lane when they try to return to the magic business. Right away they are pulled back into detective mode--but, it looks like magic is involved. 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.
