CH4 Lonk Dead no inmates

[Doc Lach]

Hi,

I have just been playing through, and I've gotten up to CH4, was advised by the pirate to get help from the inmates, went upstairs, killed Lonk, the inmates aren't anywhere to be found, all the doors are locked, and now I can't get anywhere. Can anyone help? Irenicus keeps trying to instant death me with Wish, so I deathwarded my characters, then I summoned enough creatures to waste all his spells, then I summoned some mountain bears and had them kick his *insert expletive* to *insert expletive* - they did around 600 damage!, then they unsummoned and he was still alive and still trying to wish me dead! (My last non-quicksave / non-autosave was 20 hours ago!)

Can anyone help?
