You spin around as quickly as your somewhat clumsy, half-transformed body will allow as the keening wail of an approaching siren assaults your ears, then freeze, icy fear running through you. Had that woman called the police in her frantic state to report seeing a "monster"?
A moment later, it appears the answer is "yes." A patrol car rolls to the edge of the alleyway you'd just emerged from. The siren - painfully loud to your new ears - thankfully cuts off as the vehicle stops, although its lights continue to strobe. Just your luck that a unit was down the block instead of several miles away. The doors open, two officers stepping out and heading to the alleyway. You can't help but notice their tense postures, clearly alert.
You know they're probably looking for a nut-job in a crazy outfit, one who just scared the daylights out of a passing woman, and not a man actually halfway transformed into a goat. However, you suspect that would be a moot point if they actually found you, with a trip to a laboratory somewhere figuring prominently in the future.
Your hoof makes a clopping noise on the pathway as you take an uncertain step backward. Bumping into the edge of the fountain, you turn and lift yourself up with your hands, but are still unable to stand entirely upright. A glance back through the trees to the edge of the park confirms that the car is still there, and the officers still in the alleyway, but they'll come into the park sooner or later. You know that if they spot you, you can't outrun them in this clumsy half-beast body.
