As with Sherlock Holmes, you must use your skills of observation to identify the difference in the two images presented before you. If you get stuck, click on the pipe for a hint, and you can also use the magnifying glass by clicking on its icon on the lower left of your screen. To play simply use your mouse to click on the area where you have found a difference between the two pictures, but you will need to look very carefully as this game really isn't elementary! Oh, and by the way, the clock is ticking indubitably.
