Her Code, His Downfall

1.

It was 3 a.m. when an Instagram DM lit up my phone screen.

I opened it. A selfie of my husband, Jack Carter, and his executive assistant, Sienna Shaw. They were in bed together, the signature wallpaper of a boutique Napa Valley hotel in the background.

Sienna had even added a caption: "Hey, Eleanor. Jack's all tired out tonight. He fell asleep at my place ;)"

I stared at the photo of my husband's sleeping face. A single thought flashed through my mind.

Okay, Sienna. Challenge accepted.
