Mrs.Allen stayed with her most of the night.

As to the other servants, they had all gone to bed, and the alarm did not reach them until just before the police arrived.

They slept at the extreme back of the house, and could not possibly have heard anything.
So far the housekeeper could add nothing on cross-examination save lamentations and expressions of amazement.
Cecil Barker succeeded Mrs.Allen as a witness.

As to the occurrences of the night before, he had very little to add to what he had already told the police.

Personally, he was convinced that the murderer had escaped by the window.
