Tick had felt so relieved that his dad believed his story and wanted to help, the whole Alaska expedition didn’t really hit him until the next day when his dad told him he’d bought airline tickets. His dad seemed to think they could find out who mailed the original letter and get more information from him or her. Tick thought a trip to Alaska seemed plenty exciting all by itself, and he could barely stand having to wait ten more days.

Every day of Christmas vacation, Tick and Sofia exchanged e-mails, finally getting into a consistent groove of answering questions and learning more about each other. Tick could tell Sofia was feisty and confident—not someone to mess with unless you wanted a nice kick to the shin, or worse. She was also very smart, and Tick rarely noticed a language barrier. He felt like they were similar in many ways and he found himself liking her very much. They even played chess online, though it took almost a week to finish one game because of the time difference.

Sofia was the first to figure out the last piece of the fourth clue—the first letter of the special place. At first, Tick worried they were violating some rule by helping each other with the clues, but Sofia pointed out that none of the letters said they couldn’t. In her opinion, the guy in charge should be impressed they’d had the initiative to seek out others and collaborate.

Tick felt dumb when Sofia told him the answer.

I only ask that the name of the place begin with a letter coming after A and before Z but nowhere in between.

Tick already suspected the clue pointed them to a cemetery, but it was Sofia who explained that cemetery began with a “C,” a letter that was certainly after A and before Z in the alphabet. Also, the letter was nowhere to be found in the word “between.” That’s what the sentence had meant, which now seemed painfully obvious to Tick.

They wondered about which cemetery to go to, since any decent-sized town had more than one. But the wording of the clue made it clear that the particular place they went to didn’t matter, as long as it was a cemetery. Sofia would choose one in her hometown at the appointed time, and Tick would do likewise.

Of course, both of them recognized how strange it was that they had to go to a graveyard but that it didn’t matter which one. But everything about the whole mess was odd, so they were getting used to it.

Tick was really happy to have found Sofia; for the first time in a long while he felt like he had a friend. Yeah, she lived in Italy and liked to beat up boys, but beggars couldn’t be choosers. He couldn’t wait to get the next clue and talk to her about it.
