instincts vs tail

I turned to walk up to the station, stubbornly putting my money back in my wallet with my stiff left hand as I walked, and Mouse walked beside me. The hair on the back of my neck suddenly crawled, and I looked up at the reflection in the glass doors as I approached them.
A car had pulled up on the far side of the street behind me, and was stopped directly under a No Parking sign. I saw a vague shadow inside the car, a white sedan I did not recognize and which certainly wasn't the dark grey car that had run me off the road earlier. But my instincts told me I was being tailed by someone. You don't park illegally like that, in front of a police station no less, just because you're bored.
Mouse let out a low rumble of a growl, which made me grow a shade more wary. Mouse rarely made noise at all. When he did, I had begun to think it was because there was some kind of dark presence around-evil magic, hungry vampires, and deadly necromancers had all earned snarls of warning. But he never made a peep when the mailman came by.
So adding it up, someone from the nasty end of my side of the supernatural street was following me around town. Good grief; at least I usually know who I'm pissing off, and why. By the time an investigation gets to the point where I'm being followed, there's usually been at least one crime scene and maybe even a corpse or two.
Mouse growled another warning.
"I see him," I told Mouse quietly. "Easy. Just keep walking."
