He hoped to go in by one door and out by the other, but the crowd prevented him, and he had to turn back and face the _sbirri_.

One of them followed him, having probably caught sight of the blood upon his hose.

Then Bibboni resolved to have done with the fellow, and rushed at him, and flung him down with his head upon the pavement, and ran like mad, and came at last, all out of breath to San Marco.

And this they must have done at the traghetto di San Spirito.

Neither the church nor the traghetto are now in existence, and this part of the story is therefore obscure.[226] [Footnote 226: So far as I can discover, the only church of San Spirito in Venice was a building on the island of San Spirito, erected by Sansavino, which belonged to the Sestiere di S.Croce, and which was suppressed in 1656.
