A teacher is dead, murdered by two of his students in front of the whole school.

Right in front of Jackson Jones.

But Mr Joseph was a good man - people liked him, respected him. How could those boys stab him and jog away like nothing had happened?

Unable to process what he has seen, Jackson begins his own investigation: everyone knows who did it, but as Jackson uncovers more about the boys, he becomes convinced that people need to understand why.
