Easily 3.75 stars! First, I didn't realize all the different ways you could make a grilled cheese and this made me hungry every time I picked it up. Secondly, Lyle sucks big time. Third, I felt like the mystery was done super well and kept me on my toes. I spent most of the book believing I knew who the killer was and it ended up being someone who wasn't even really on my radar. I do wish there had been more details with the characters, some did feel a little stiff to me.
