Corset.

To start with, discard all of the previous claims that the 'colour and position' of the ten symbols on the right hand side of the fireplace is significant. It might be but i sure didn't find any use for it.

I like many of you probably recognised two of the symbols instantly: the male symbol and the female symbol. These symbols were easy to memorise, as was their order in the list.

After many a second of ferocious clicking on the books, i then realised that both the list of symbols and the list of planets were significant in which order one had to click the books to make the lettering appear ('trenchcoat astrologer').

At that point it occured to me that the symbol for males was equivocal to the planet mars in the puzzle, and the same went for the female symbol for venus (men are from mars, women are from venus). It also occcured to me that the symbol for mercury (being a hot planet) was the devil, i.e. hell. So logicaly, the earth had to be between the female and male symbols on the list. It was the circle with the cross in the middle.

It also then occured to me that all three of these symbols were on the top row of the coloured symbols to the right of the fireplace, and that they seemed to stand out amongst the others. So, being the inquisitive chap that i am, i went through the process of revealing all the letters, and then wrote down all the symbols and their corresponding letters.

Lo and behold, venus, earth and mars (woman, circle, man) were the first ones i wrote down because of my previous deductions, and there, right before me, was the password: Corset. What this has to do with the solar system, we will never know.
