In the autumn of 1607 the tempest broke upon their heads.

Virginia was removed from Monza to the convent called Del Bocchetto at Milan; and on November 27 the depositions of the abbess, prioress, and other members of S.Margherita were taken regarding Osio's intrigues, the assassination of Soncini, and the disappearance of Caterina.
Among the nuns who had abetted Osio, the two most criminally implicated were Ottavia and Benedetta.

Their evidence, if closely scrutinized, must reveal each secret of the past.

It was much to Osio's interest, therefore, that they should not fall into the hands of justice; nor had he any difficulty in persuading them to rely on his assistance for contriving their escape to some convent in the Bergamasque territory.

We may wonder, by the way, what sort of discipline was then maintained in nunneries, if two so guilty sisters counted upon safe entrance into an asylum, provided only they could leave the diocese of Milan for another.[190] On the night of Thursday, November 30, 1607, Osio came to the wall of the convent garden, and began to break a hole in it, through which Ottavia and Benedetta crept.
