First you have to move your mouse forward and back really quickly about four or five times.Then when you're untied you keep moving right.Go through the door and keep moving left.DON'T JUMP THROUGH THE FIRST GAP!Jump through the second gap and move right.Jump through the gap above the guard and move right again.Wait untill the guard walks to the edge of the platform on the other side.Then follow right behind him when he turns around.Jump on the couch and through the gap.Then use the Black Widow keycard at the door.Go though it.Then battle Black Widow.To beat her catch four peices of art and then click on the lever and twirl the mouse as fast as you can!Dodge the bomb and catch four more peices of art.Continue these steps for about eight or nine sets.Then the henchman tackles her.Voila!Past the Black Widow's lair.Hope this helps.
