Who’s Home?
He had just landed, and his first move was to visit Philip’s house and then surprise her because they lived opposite each other. He imagined her returning home, probably planning to get the kids from school. And then came out to surprise her on her way out, so they both would pick up the kids together from school. He ensured his wife wouldn’t be suspicious of his activities, and because he knew Philip would be at home, he didn’t bother to let him know. To his amazement, Philip’s flat wasn’t locked.
