He served up pasta and mushroom soup that smelled amazing.

I realized with a start that I'd rarely tasted his cooking before.

Shouldn't it mean something that he was doing this for me now?

But that photo kept flashing through my mind - his tender smile, that pink diamond bracelet.

The memory felt like a knife in my heart.

"To us." Richard clinked his glass against mine, his smile warm and familiar.

"To the most amazing wife a man could ask for."

I echoed his toast, but the juice tasted like vinegar going down.

That mysterious photo and message kept gnawing at me.

Was someone trying to tell me something?

Warning me that my perfect marriage wasn't so perfect after all?

After our late-night dinner, I went through the motions of cleaning up, my mind a thousand miles away.

In the bedroom, Richard came up behind me, wrapping his arms around my waist.

"Let me show you how sorry I am about missing our anniversary," he whispered, his lips finding that sensitive spot below my ear.

I pulled away, my voice shaking.

"Our anniversary ended at midnight. It's almost dawn."

He gave me a long look before heading to the bathroom.

"You're tired. We'll make up for it another time."

Once he was gone, I pulled out my phone, staring at that damning photo until my eyes burned.

Sleep was impossible that night.

I lay beside my husband, listening to his steady breathing, while my mind spun with possibilities.

Once you start doubting someone you love, every memory becomes suspect, every gesture questionable.

The next morning came too soon.

I dragged myself downstairs, only to be stopped by our housekeeper Mary's cheerful voice.

"Mrs. Blackwood, we have a special visitor today."

"Oh?" I managed, still groggy from my sleepless night.

"Miss Susan is here." Mary nodded toward the living room.

There she sat, Susan Blackwood, in a powder-blue dress that probably cost more than most people's monthly salary.

My husband's step-sister looked every bit the society princess she was, not a hair out of place despite the early hour.

Then I saw it.

The pink diamond bracelet. The exact same one from the photo.

My world tilted sideways.

Susan was Richard's step-sister - no blood relation, but family all the same.

She was actually a few years older than him, had been in his life since their parents married when he was sixteen...

The tender smile in that photo flashed through my mind again.

Black spots danced in front of my eyes, and my knees buckled.

The last thing I remembered was Mary's startled cry as I started to fall.

"Sophia!"

Richard caught me before I could hit the ground, his strong arms pulling me against his chest.

Despite his warmth, I felt ice-cold inside.

"You're white as a sheet. What's wrong?"

His concerned expression was perfect - exactly what you'd expect from a devoted husband.

Too perfect?

"I'm fine," I managed, forcing a smile.

"We have a guest. I should go say hello to Susan."

"You're clearly not well."

Richard frowned, calling to Mary to phone our family doctor.

"Let me handle this."
