While my husband was out of town for work, I brought a cake to his best friend’s widow. I thought I’d find her grieving.

When the door opened, the man standing in it was my husband — and behind him, the widow, one hand resting on a pregnant belly.

Chapter 1 — The Sweet Scent

My own liberation didn’t begin with a screaming argument or a midnight confession. It began with the smell of sugar and vanilla.

Late that afternoon, after escaping my real estate firm on Michigan Avenue, I stopped at a little bakery near the entrance of our Chicago condo complex.

The autumn rain had just quit, leaving the pavement slick and mirror-bright with passing headlights. My plan was selfish: one slice of raspberry tart, a small reward after a day of board meetings and demanding clients.

But as the cashier boxed my pastry, I thought of Khloe.

She lived in the next building over, the South Tower — the widow of my husband’s late best friend. Her husband, Tom, had died in a highway collision, a tragedy made worse by the fact that he’d swerved to save my husband, Michael.

Ever since, Michael carried it like a debt. He was always over at her unit fixing a pipe, resetting a breaker, assembling furniture.

At first my heart broke for her. Widowed so young, stuck in a quiet apartment with her elderly father-in-law, Robert — I couldn’t imagine it. So whenever I bought myself something nice, I got her a portion too.

I believed generosity was the decent thing. I believed my husband was a man of honor and gratitude. And most dangerously, I believed that if there was an invisible line between a man and a grieving woman, Michael would never cross it.

So I asked the cashier for a second box.

I drove down into her building’s parking garage to get out of the last of the drizzle. I hadn’t called ahead. Khloe texted me all the time about how lonely she was, telling me her door was always open.

I came off the elevator on the fourth floor. The corridor was oddly silent, the amber lights throwing a yellow glow over the tile, a faint smell of lemon cleaner in the air.
