Zenumist and the Missing Alchemist - Please help!

Hello,

This quest is driving me nuts. I've done everything up to the point where I'm supposed to search for clues in the 'Home of the Missing Alchemist'. I clicked on the 'Picture Frame' and according to Strategy Wiki I'm also supposed to click on the candle, but there's nothing to click on near the candle except for the 'desk'. Have any of you completed this quest? Do you know what I'm supposed to click on?

Please help! tyvm

I stumbled across it using my NPC chat button. It's called wall, says there's spider webs. I know it's upstairs above the desk... or around that area.

Thank you SirEmily
