The Secret in His Pocket

From the back cover

On their son's first day of school, a wife uses her husband Dylan's phone to link the student portal and finds a pop-up saying the number is already registered to Leo Chen — his late brother's son. Dylan explains that his widowed sister-in-law Grace is overwhelmed and asked him to link the app so he could catch school notices. His answer is seamless, yet the wife cannot shake the feeling that something is wrong.

Later that night she finds a small foil packet in the pocket of the navy jacket she gave him. It is not the brand they have always used, and his explanation about a lakeside hotel trip does not hold: she remembers the packet from that room was blue, and this one is red. The next morning Dylan is all warm breakfasts and booked tables, and then she finds his work phone left behind on the coffee table, its messages locked away.

Ten years of marriage, four days off every month spent at Grace's place, and a husband who never saved their own son's teacher's number — the wife begins to question how much of her life is built on trust.
