about midnight
`` Me take great care to kiss very much , '' said Marianna , simpering . `` I shall trust to you ; but be careful not to recognise any of the rest of us ; and now , my sweet Ada , I must bid you farewell . Be prepared to-morrow night for our exploit . Somewhere about midnight I hope to be with you . Put on some dark , close-fitting dress , which is less likely to be seen in the dusk than a light-coloured one ; and if you could procure capotes from Signora Nina , such as she now wears , it will be still better . Should we be met by any of the islanders we may be mistaken for their friends . Our present purpose is to escape from the harbour , and to leave the mistico in lieu of the boat we take .
