One of the benefits of the unlife was having all the time in the world... unless you lacked the patience.
The compound was especially challenging, but the watch revealed two important details: This is where Aislyn spent a great deal of her time and the night manager was the vulnerability.
Not surprising, there was little to learn from the day movements. Instead, Jacque called on his ghoul to start accompanying him with the evening. He instructed her to first follow the plump woman after her standard 9 PM departures. He was of course curious about where she went with Aislyn, but hadn't settled on the approach yet. He needed to know more about the gatekeeper first.
Jack is trying to learn more about the plump woman's living situation. Home address, living arrangements, vehicles, if multiple people are in the domicile and possibly even discreetly sift through mail to learn more about her name or confirm if others live at the location.
