Tranquillina is interested in acquiring some good summae on mundane Abilities, specifically Medicine and Chirurgy, for the covenant library. The cost of such books is nearly trivial (a pound of silver each or thereabouts, if I remember correctly) - it would just be a matter of locating suitable summae for sale or copy. Would the troupe consent to Tranquillina just paying a Redcap a little bit of vis to go to the trouble of locating and procuring suitable summae? Or should it be more of a story (or otherwise non-automatic) event? Either way, how should we work out what the stats of the books are?
