The little house in Trastevere was shut up, but the gardener had the keys, and came twice a week to air the rooms and sweep the paths and water the shrubs.

He was to be informed by Settimia of Regina's return in time to have everything ready, but he did not expect any news before the end of September; and if he came regularly, on Tuesday and Saturday, and did his work, it was because he was a conscientious person in his way, elderly, neat, and systematic, a good sort of Roman of the old breed.

But if he came on other days, as he often did, not to air the rooms, but to water and tend certain plants, and to do the many incomprehensible things which gardeners do with flower-pots, earth, and seeds, that was his own affair, and would bring a little money in the autumn when the small florists opened their shops and stands again, and the tide of foreigners set once more towards Rome.

Also, if he had made friends with the gardeners at the beautiful villa on the Janiculum, that was not Corbario's business; and they gave him cuttings, and odds and ends, such as can be spared from a great garden where money is spent generously, but which mean a great deal to a poor man who is anxious to turn an honest penny by hard work.
The immediate result of this little traffic was that the gardeners at the villa knew all about the little house in Trastevere; and what the gardeners knew was known also by the porter, and by the other servants, and through them by the servants of other people, and the confidential valet told his master, and the maid told her mistress; and so everybody had learned where "Consalvi's Regina" lived, and it was likely that everybody would know when she came back to Rome, and whether Marcello came with her or not.
He had not taken Folco's advice, much to the latter's disappointment and annoyance.

On the contrary, he and Regina had left the Engadine very suddenly, without so much as letting Corbario guess that they were going away; and Regina had managed to keep Settimia so very busy and so constantly under her eye that the maid had not been able to send Folco a word, warning him of the anticipated move.
