If there is even the slightest slight shadow of a hint anywhere, it lies in the very meagerly suggestive fact that "spalleggiato" carries our word "egg" in its stomach.

Well, make the most out of it, and then where are you at?
You conjecture that the spectator which was smoking in spite of the prohibition and become reprohibited by the guardians, was "egged on" by his friends, and that was owing to that evil influence that he initiated the revolveration in theater that has galloped under the sea and come crashing through the European press without exciting anybody but me.

But are you sure, are you dead sure, that that was the way of it?
No.

Then the uncertainty remains, the mystery abides, and with it the charm.

Guess again.
If I had a phrase-book of a really satisfactory sort I would study it, and not give all my free time to undictionarial readings, but there is no such work on the market.
