Through the bars on her window, he watched her as she sat on the couch with the boy. He couldn’t see them clearly, as there was a gauze curtain in the way, but he recognized the shapes of them, the larger and the smaller, nestled close together on the sofa in the living room.

He’d made it his business to learn her schedule. During the week, she schooled the boy until three in the afternoon, whereupon on Mondays through Thursdays she took him to the YMCA for his swimming and basketball lessons. While the boy was at the facility, she never left him—whether he was in the pool or on the court, she was perpetually seated on the benches where the children left their warm-ups and their little bags. When the boy was finished, she waited right outside the locker room for him, and after he got changed, she drove him straight home.

Careful. She was so very careful—except for the fact that the rhythms of her life never changed: Every night except Sundays, she made the boy dinner at six; then the babysitter showed up at eight o’clock and she took off, going to St. Patrick’s either for confession or prayer group. After which she went to that godforsaken club.

He hadn’t been inside the Iron Mask yet, but that was going to change tonight. His plan was to trail her for hours while she worked as a waitress or a bartender or whatever she was, learning more about her and how she lived. God was in the details, as they said, and he needed to know everything.

Glancing into the rearview mirror, he fussed with the wig and the mustache he was using as a disguise. They weren’t sophisticated, but they hid his features well enough, and he needed them for a variety of reasons.

Plus he relished the feeling he got when he was invisible to her; the thrill of watching her when she was unaware of it was downright sexual.

At seven forty, a sedan pulled up in front of the house and an African-American woman got out. She was one of three babysitters he’d seen this week, and after following one of them home and seeing where she went the next morning, he’d learned they all came from a social service called the Caldwell Center for Single Mothers.

Ten minutes after the sitter went inside, the garage door trundled up and he ducked lower in his seat—because two could play at the extra safe game.

Seven fifty. Right on time.

His woman backed out into the driveway and waited as the door shut tight, as if she were worried that one of these times it wouldn’t make it all the way down. When it was finished doing its thing, her red brake lights went out and the car reversed into the street and took off.
