A Doctor, pale with dark hair.

The instant you saw him, you knew you had to have him. A strange thought, seeing as at the time he was covered up to his elbows in blood and working to save the life of the man you’d screwed up assassinating.
You had just managed to make a preliminary slice across the fat Duke’s stomach when an unexpected knock sounded upon the door to his chambers. Caught shamefully unawares you somehow managed to let the man slip from your grasp and call for help. Cursing your inattentiveness, you dashed out the window as guards burst into the room.
You didn’t go far, knowing that he had to die by your hand, and as soon as you saw the opportunity you slipped back inside and hid in the shadows.
There was still a single guard, hovering nervously as blood spread across the floor, but otherwise the Duke and a doctor were alone. The wound was very deep, but still salvageable, if the doctor was good enough. And this one looked like he just might be.
Young, almost a boy still, but with the bluest eyes you’d ever seen and an intense aura of command. You watched his hands moving with confidence and skill, sewing up your handiwork.
Unfamiliar feelings swirled in your heart but you did recognise desire. And possessiveness; somehow you had to get him and keep him, away from anyone else.
'Today was a day for surprises', you mused; already plotting.
