If you confront the man
You use your shop equipment to make a special telescoping knife, it wraps around your wrist and flicks out when you flex your thumb. You practice flicking the blade in and out and doing forward flicking thrusting movements to drive the blade hard. You think you have it down. You take a couple shots of brandy to nerve yourself up. You slip on your long sleeve silk shirt and make like you are going for a walk. As you walk along you pull out a Marlboro Light and fumble in your pocket for the lighter you "Forgot". You glance at the smoking man as if seeing him for the first time. You walk up to him saying, "Hey man, have you got a light?". The man keeps his cool and causally reaches into his pocket to pull out a F B I zippo, you do your practiced flick and thrusts, burying the blade into his belly, he collapses into your arms and you "Help" him back to your lab. You drag him inside and drop him roughly to the floor, he is still alive but in shock.
