Secret one
In Hauptman's office, there is a picture of Hitler:

Shoot it, revealing a switch:

Pull the switch:

and a secret door opens on the wall opposite:

allowing access to a secret room:

Secret two
It looks like the room that sniper used isn't accessible:

But hey - we can climb this drainpipe:

and then jump onto the window box before entering the sniper's room. Oh, looks like he's asleep:

The room itself is a secret area:

As an added bonus, Dr Merkwurdigliebe will now go for his evening walk. If only there was some way we could show him our appreciation of his nice velvet smoking jacket:

Secret three
Find this cellar door:

It's padlocked.

Shoot the padlock off, and go through to the ladder:

go down the ladder, walk along the passage, and up a second ladder:

which takes is into Dr Merkwurdigliebe's backroom.

(note: if you solve secret three before secret two, the good Doctor will be working in his lab).
Secret four
Go down to the winecellar:

The bung on the left barrel is suspicious - push it:

this makes a secret door open in the wall to the left of the barrels:

go through to enter a secret chamber:

In the room with the attractive lingerie lady, there's a box at the foot of the bed:

Kick open the box, to reveal some treasure:

Notice - the lingerie lady is no longer cowering in fear, but is much more friendly. Ladies like men who're good at kicking stuff, apparently.
