Unbreakable Code

Mr. Quisling is definitely up to something mysterious, and Emily and James are on high alert. First, there's the coded note he drops at a book event. Then they uncover a trail of encrypted messages in Mark Twain-penned books hidden through Book Scavenger. What's most suspicious is that each hidden book triggers an arson fire.

Domnul Quisling cu siguranta pune la cale ceva misterios, iar Emily si James sunt in alerta maxima.
