How do I locate the conduit for the power source?

Are you in Mr. Gordon's study? If not, come back when you are.

Look at the PAINTING over the wine tasting table for a hint. (You will only be allowed to examine this after your host is distracted.)

In the painting, Mr. Gordon (the present-day one) will be discreetly pointing out the conduit.

Now look directly at the fireplace. Tap for a closer look.

Do you see it? Cleverly hidden in plain sight. Remember it for later.
