Do you have a rakish soul?

I often wonder if people have a rakish side. Here is an excerpt from My Darcy Mutates...about it.

Mr. Fitzwilliam Darcy looked into the mirror and, startled, cried out, “Who are you?”

He turned to look at the man who stood a mere foot from him. How could it be possible? The man looked exactly like him, with just the same tall frame and dark, curly hair.

While he himself wore a black overcoat, matching waistcoat and breeches and a pristine white shirt, the man had everything in reverse. His coat, waistcoat and breeches were alabaster white, while his shirt was black. The other differences were that this stranger had olive skin and a reckless grin.

“I am your rakish soul,” the man replied with a wink, and rubbed his hand over his thigh.

“Rakish soul? I do not believe it. You have the manner of an imposter.”

“Do I not look exactly like you, Good Darcy?”

“My complexion is not so dark.”

“Well, people normally associate rakish behaviour with the shadows. As your blackguard, I take on the darker complexion. But tell me, are not my eyes, nose, mouth and voice exactly like yours?”

Ignoring the question, Darcy said with conviction, “I do not have a rakish soul. I am an honourable man.”

“Ah, but you are wrong. Every human is born evil. Only upbringing and education prevent them from staying evil. Still, I can reassure you, to a point. You were born with only a tiny bit of rakishness, not evil at all. You are mostly a good man, truth by told.”

“You are a fake!” Darcy accused, but thoughts rose to assail him. Am I turning mad? I am about to attend the Meryton Assembly. Should I instead stay in and send for a doctor for myself?
