IN the VERY TOP of the Tourpee Tourance...
The spy at the electrified building is the second spy you have to rescue, as they have to be saved in order. The first spy to be rescued is at the Docks, and when you save him, you receive the Laser Pen, which can cut through the attic window bars and reach the second spy.
The electrified building on Toupee Terrace is where you will find the second missing spy. Before you can rescue him, you have to save the first spy at the Docks. The first spy will give you the Laser Pen that can cut through the bars on the roof window.
You have to free the "first" spy, at the Docks, before you can rescue the "second" spy, who is in the attic behind the bars. The first spy will give you a Laser Pen that can cut the bars. (see related question)
You need the Laser Pen. The spy in the attic is the "second spy" to rescue, because the first spy you rescue has the Laser Pen. Get the Chameleon suit from Spyglass Eyewear, and rescue the first spy on the docks. Then you can come back to the electrified building and save the second spy. (see related questions)
save the second spy
when you save the first spy at the docks he gives you a laser pen. When you get the laser pen you have to go the the brick building with the shock windows and climb to the top. When you get to the top there are bars covering a window so you have to click on it and the laser pen will show up. Then you hold down your mouse and drag the pen across the bars and you are in!
if you mean the bow you get it after you save the second spy
Take the Laser pen and go to the electrified building on Toupee Terrace. Climb the windows by jumping when they turn off. Use the laser pen to cut the attic bars and save the 2nd spy.
you go get the third one
The bars can be cut with the Laser Pen, which you get from saving the spy at the dock. The three spies have to be saved "in order", to get the spy devices you need. The first spy, at the docks, is rescued using the Chameleon Suit. The second spy is saved using the Laser pen. The third spy, on the rooftops above Balding Avenue, is rescued using the Grappling Bowtie that the second spy gives you. (see related question)
You reach the rooftops above the Grease Monkey garage after you rescue the spy from the electrified building on Toupee Terrace. The first spy to save is at the docks, the second on Toupee Terrace, and the third on the rooftops, because you need tools from the first to save the second, and from the second to save the third. The only way to the building tops is using the Grappling Bowtie from the second spy. (see all three at the related question)
If your talking about the bars on spy island, you need to get a laser from one of the agents you save.
