"Alex, this is all going to sound crazy, but you have to trust me. I can no longer act in my own time, but you can. That is why I chose you to solve the riddles of Professor Corvino. I know you are afraid now and do not feel up to it, but know that you have what it takes to accomplish this mission. The fate of the world is in your hands." I keep rereading the e-mail trying to figure out who this person is who wrote to me a few days ago. His directions led me to the Botanical Garden of the University of Ferrara, in Italy. I have to pass 10 tests to find a hidden object, but what will it be? For this task I will need all the help I can get.
