The Knuckle-Scarred Inspector is Indisposed

Hello fellow denizens of the bazaar, I’m wondering if any of you have tried this particular storylet option from the above titled storylet?

Having started/solved the Jack case I’ve been unfortunately precluded from said option, but the rewards seem quite substantial if the option can be repeated.

I’ve done it a few times. I think the ppa for it is 1.23, so it’s not as good as other options for making echoes. It is a nice variety of stuff, however.
