He had brought his wife's body to Rome, and had summoned the very highest authorities in the medical profession to discover, if possible, the cause of her death.

They had come, old men of science, full of the experience of years, young men of the future, brimming with theories, experts in chemistry, experts in snake poisons; for Folco had even suggested that she might have been bitten by a viper or stung by a venomous spider, or accidentally poisoned by some medicine or something she had eaten.
But the scientific gentlemen were soon agreed that no such thing had happened.

Considerably disappointed, and with an unanimity which is so unusual in the confraternity as to be thought absolutely conclusive when it is observed, they decided that the Signora Corbario had died of collapse after intense excitement caused by the disappearance of her son.

Thereafter she was buried out at San Lorenzo, with the secret, if there were any; masses were said, the verdict of the doctors was published, with the signatures of the most eminent practitioners and specialists in Italy; and the interest of the public concentrated itself upon the problem of Marcello's mysterious removal, or abduction, or subduction, or recession, or flight, from the very bosom of his family.
This problem had the merit of defying solution.

In a comparatively open country, within a space of time which could certainly be limited to five minutes, at a place whence he should have been clearly seen by Folco Corbario as soon as Aurora dell' Armi could no longer see him, the boy had been spirited away, leaving not even the trace of his footsteps in the sand.
