The Third Key

Zazie Skymm and her stepsister Luna Bunny have been at each other's throats since forever. They poke, they compete, they get crazy jealous the second the other pulls attention. Neither one has ever said why. One last night in the old family house before it's emptied. The second they're alone the old bullshit starts right back up. Zazie finds a photo of Luna sleeping in bed and the shot looks like it was taken tonight. Luna swears Zazie snapped it. Zazie swears she didn't. More pictures keep turning up. Each one shows shit that hasn't even happened yet. Fear starts kicking in, then the jealousy blows wide open. Zazie spits it out first. She never gave a damn about the people Luna dated. She hated watching her pick anyone but her. Luna shoots back the exact same truth. They don't get to figure out what any of it means, because they find the last photo. It shows them standing outside the locked bedroom. Back of the picture reads 'DON'T OPEN IT AGAIN.' One tiny problem. Neither one remembers ever opening that door.
