Everyone In My Family Has Killed Someone

I knew our family reunion wouldn't end well. But I didn't expect murder.

Maybe I should have known better. After all, everyone in my family is a killer. My parents, my siblings, my in-laws . . . even me. The deaths weren't all deliberate, of course. Accidents happen.

So when a body is found in the snow, it's clear it's the work of a Cunningham. But which one? And why?

I'll give you one clue: it wasn't me.
