The servants, likewise, must have been ordered not to release Patty, for Ray Rose was not one to do anything by halves, and if she had planned to get Patty over there, she had also planned to keep her there.
It was ridiculous, it was maddening,--but it was true.

Patty was locked in a room and could not get out.

She hadn't heard a key turn, but it must have done so.

Peeping in the keyhole, she could see that the key was in the lock, from the hall side.
Endeavouring to use her ingenuity, Patty tried to turn the key from her side by means of a button-hook, a nail file, a hairpin, and a glove stretcher.

Needless to say her attempts were unsuccessful.
"I've heard of turning a key in its own lock," she mused, but she found the feat impossible of achievement.
Again the chiming little timepiece reminded her that another quarter hour had flown.
"Half-past seven!" she thought.
