So did you figure this out or are you just doing without interior lights :-).
Strictly amateur opinion: Is this dead after 4-5 days of storage/sitting? How dead is dead? 0.2A is only about 2.4 watts. They do make courtesy lamps in that range, more often than not though they are LED's. I don't think the brain drain progression is linear, but still, if my math is close, it would take almost 18 days to draw a typical 45 Ah car battery down only 20%. Can't believe that's enough, by itself, to kill a battery in a stored car in 5 days.
2 regular guesses and some additional wild guesses.
1. Was anything added to the car that may have tapped into that circuit? Led lighting etc? (Had a Cressida with a built in cell phone that was killing batteries, wasn't on a circuit though (tapped at battery, so hard to find))
2. Short. Good luck, always fun. Pulling lights in the circuit 1 at a time may give you more info. (Example 2, Ford E-van with holes in the front timing cover. Has timing chain, not belt, so oil is in the compartment and was getting spewed out all around the front of the engine compartment. Mild short of some kind (conjecture) developed in the oil soaked electronics and it would't start after sitting a long weekend.)
Wild guesses. Outside of the above the only thing I could see that could be happening without you knowing it is in the luggage light circuit. Can't tell what the connection to the Trunk CD player off the luggage light circuit does. Also don't know if the connection to the Anti-Theft computer from luggage light is capable of a small draw. Pulling luggage compartment light should eliminate those.
Good luck. Only have 167K on our 93ES300
