Sir Giles withdrew, to look after his business at the bank. She waited
until the clock had struck the servants' dinner hour, and then ascended
the stairs to her godfather's dressing-room. Opening his wardrobe, she
discovered in one part of it a large Spanish cloak, and, in another
part, a high-crowned felt hat which he wore on his country excursions.
In the dark, here was disguise enough for her purpose.

As she left the dressing-room, a measure of precaution occurred to her,
which she put in action at once. Telling her maid that she had some
purchases to make in the town, she went out, and asked her way to
Garvan of the first respectable stranger whom she met in the street.
Her object was to walk as far as the first milestone, in daylight, so
as to be sure of finding it again by night. She had made herself
familiar with the different objects on the road, when she returned to
the banker's house.

As the time for the arrest drew nearer, Sir Giles became too restless
to wait patiently at home. He went away to the police-office, eager to
hear if any new counter-conspiracy had occurred to the authorities.

It was dark soon after eight o'clock, at that time of the year. At nine
the servants assembled at the supper-table. They were all downstairs
together, talking, and waiting for their meal.

Feeling the necessity of arriving at the place of meeting, in time to
keep out of the Sergeant's way, Iris assumed her disguise as the clock
struck nine. She left the house without a living creature to notice
her, indoors or out. Clouds were gathering over the sky. The waning
moon was only to be seen at intervals, as she set forth on her way to
the milestone.
