Look close at the oscillator right of the main workbench. The taps look like the ones in the drawing in Niko’s study. The taps (L-R) are labeled: 13, 11, 9, 7, 5, 4. The magic number is what Niko mentioned: Frequency 37. Place the building (Wardenclyffe Tower) inside the oscillator and close the box. Turn the taps to get to frequency 37. The miniature building breaks. Take the control key. Go back down the hatch and enter Niko’s study. Go to the desk. Use the control key on the tablet below the monitor. This is similar to the security video monitor lock. The aim of the puzzle is to click on five points to light up the board green. Remember there are only five chances to do so. There is a reset button below the charges panel at left. The points can be clicked on in any order. The monitor asks for a password. Remember the clue heard in Niko’s diary and shown by the pigeon. Enter the number of the 1902 patent: 1119732. Press the Enter key. Press the play arrow. Watch the unedited video and see Niko’s killer. Take the USB flash drive out from the bottom of the monitor. A sound is heard. Turn around and see that the door has a glow. Exit and Nancy says that it is Niko’s security. All the electronics got fried and the flash drive has been erased. Go to the workshop and talk to Ryan. She advises you to make a Faraday cage. She gives components in a cardboard box. Take the items. Go to the workbench where the robotic cat is. Take a rocket USB drive from the container on the top shelf. Review the Electronics (Tesla coils) book in inventory. The book has an article about making a Faraday cage. It says that one can make a cage from a cardboard box wrapped in aluminum foil with a ground from a paper clip and a binder clip. Read also about strike rings and lightning rods. Go to the photo lab. Open the supplies cabinet above the microscope. Take an empty silicon wafer wrapper made of aluminum (left side). Go to the lounge.

Lounge
Go to the desk beside the bookcase in the lounge. Place the empty cardboard box on the table. Use the aluminum wrapper on the cardboard box. The box is now aluminum wrapped. Take a paper clip from the tray. The straightened paper clip is inserted on the box. Take a binder clip and attach it to the paper clip. Pick up the Faraday cage. Set the alarm to nighttime. Go upstairs and talk to Ellie. She will get help and advises you to talk to Gray. Talk to Ellie about everything else. Go down to security and talk to Gray. He will take care of Victor while Nancy gets the evidence. Learn about his relationship with Niko and what happened to him. Go back to Niko’s study. Look close at the monitor. Insert the rocket flash drive on the USB port. Press the down arrow beside the drive to download the video. Pull out the rocket drive. Nancy automatically places the drive in the Faraday box. Exit the study. Exit to the main lab. See Gray knocked out on the floor. Exit through the double doors and meet the killer.

Lab
Nancy is knocked out and wakes up inside the Faraday cage. While the killer explains why Nancy was chosen, Nancy looks around for a way out. When an active cursor is obtained, look close at the lightning rod lift box on the wall of the cage. Open the box and see that it is an empty circuit board. Place the components from Ryan on the board. The components are on the left side. The Tesla coil user guide and the schematic are on the right side. Review the book to learn about the components and their icons in a schematic. Study the schematic to find out where to place which components. Follow the line of the components and compare that to the empty circuit board. Place the components on the empty circuit board based on the schematics. Right click to turn the components. Watch what happens to the killer. Another case solved by Nancy Drew!
