That afternoon, Liam drove down to the nearest hardware specialty store in town. He didn't just buy a new lock; he bought a fortress in a box.
He purchased a commercial-grade, biometric smart lock. It featured a titanium-reinforced steel core, a drill-resistant cylinder, and an auto-locking mechanism that required either a recognized fingerprint or a complex encrypted passcode to open. Along with it, he bought a three-inch steel strike plate and four-inch screws to secure it directly into the wall studs, making the door practically kick-proof.
He spent the entire evening installing the beast of a lock, along with a discreet 4K security camera tucked under the eaves of the porch. When he tested the lock, the heavy steel deadbolt slid into place with a satisfying, echoing thud.
Let Susan try to get past this.
Two days later, Liam had to drive into the city to finalize some paperwork for his architecture firm. He was sitting in a coffee shop downtown when his phone buzzed. A notification flashed on his screen: Motion Detected: Front Porch.
