madness mad-nes n (14c): the quality or state of being mad: a: rage b: insanity c: extreme folly d: ecstasy, enthusiasm.

And, added in the margins of the dictionary owned by James Tremont, the ninth duke of Parkerton, one additional definition:

e: the state of finding oneself mistaken for a solicitor by a duke-hunting beauty who needs to be enthusiastically taught the true meaning of love.

Rage, insanity, extreme folly, and ecstasy will most likely be involved.
