You throw a smoke bomb at him and run past him to the window be fore he sees you.
you use the smoke bombs to make the guard blinded for a few seconds then quickly get past him.
You don't actually. In the Black Widow's lair, go past the first guard and climb up above and behind him. When the guard on the next level walks over and turns back to the right, jump across and follow her to the springy chair.
To get past the guards, go all the way to the left, climb above the boxes to avoid the male guard, and when you see the (female) guard on the third level, follow her and bounce up on the sofa to the locked door. (Use the key card to open the door)

Duck past the window, (arrow pointing down/yellow), to get past the security room, then when you enter the statue room, hide behind the statues. You then go out into the hallway and climb the rope above the painting and wait.
throw a ninja star at it
To reach Nikola Tesla when he is held in the Coal Car, climb through the roof door in the baggage car, then work your way forward (right) on top of the train. You can't get past the guard at the back of the train until you discover what Erik Weisz (Houdini) knows about the stolen items. Once you confirm what has been taken from Tesla's cabin, you can slip past the Rube Goldberg alarm arrangement by climbing up, crossing the first gap, and dropping down through the second (you will not wake the guard or his dog).
The female "security guard" stays in the Security Room at the museum. The female guard who works for the Black Widow is on the third level of the lair, and walks back and forth to the left. When you climb past the first guard, jump up behind and carefully follow her until you reach the chair. Jump in the chair and bounce to the left.
you have to use your ninja star and cut the line
In the Black Widow's lair, go under the first guard, to the second opening, then climb the box above him to the left. When the female guard comes left and turns back to the right, jump up and quietly follow her until you can jump to the chair. Bounce up and left to reach the key card door.
