Tuppence bent lower still. It was only a breath.

"Mr.--Brown----" The voice stopped.

But the half-closed eyes seemed still to send an agonized
message.

Moved by a sudden impulse, the girl said quickly:

"I shan't leave the flat. I shall sit up all night."

A flash of relief showed before the lids descended once more.
Apparently Mrs. Vandemeyer slept. But her words had awakened a
new uneasiness in Tuppence. What had she meant by that low
murmur: "Mr. Brown?" Tuppence caught herself nervously looking
over her shoulder. The big wardrobe loomed up in a sinister
fashion before her eyes. Plenty of room for a man to hide in
that.... Half-ashamed of herself, Tuppence pulled it open and
looked inside. No one--of course! She stooped down and looked
under the bed. There was no other possible hiding-place.

Tuppence gave her familiar shake of the shoulders. It was
absurd, this giving way to nerves! Slowly she went out of the
room. Julius and Sir James were talking in a low voice. Sir James
turned to her.

"Lock the door on the outside, please, Miss Tuppence, and take
out the key. There must be no chance of anyone entering that
room."
