Everyone In My Family Has Killed Someone: Benjamin Stevenson

Everyone in my family is a killer. Everyone in my family is a suspect.
But which of them is a murderer?
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.
But a piece of advice? Never trust a Cunningham…
