The total at the bottom was four thousand one hundred and eighty dollars, paid in full on a corporate credit card ending in four zeroes.

Right above the total, printed in clear black ink, was the item description: a fourteen-karat white gold diamond tennis bracelet.

I remembered Sloan’s strict instruction from three nights ago, when she told me to stay in my room after six o’clock every evening because the kitchen was off-limits.

She hadn’t wanted me in the kitchen because that was when the delivery drivers brought the designer shoe boxes, and that was where Mark dumped the receipts from their shopping trips.

I folded the receipt twice, slipped it deep into my cardigan pocket, and backed away down the dark hallway.
