Ember talked through the door for five minutes. His remarks ranged from persuasive promises to threats, which lost nothing from being delivered in a chilly whisper. At the end of the five minutes he put his shoulder against the lock and broke it. He found an empty room and a locked cupboard. When he had broken the cupboard door and discovered nothing more exciting than Renata’s schoolgirl wardrobe, he went to the open window and stared incredulously at the drop to the terrace. Jane had turned the corner of the house and was out of sight.

Ember came downstairs with the knowledge that he must complete his business quickly if he meant to bring it to any conclusion other than disaster.

He went straight to the library and rang up the Withstead exchange.

“The young lady who was telephoning just now, did she get the number she wanted? She did? Would you kindly tell me which number it was?”

There was a pause, and then the information came: Sir Julian Le Mesurier! There was certainly no time to be lost. Molloy and his daughter both traitors, both spies, both in Government pay! Molloy should be reckoned with by now, and some day without fail he would reckon with Renata.

He came into the hall, and released the spring of the hidden door. As the panel turned under his hand, he heard the purr of a motor coming nearer. It drew up. The bell clanged. Mr. Ember stepped into the darkness and closed the panel behind him.

“And Miss Molloy?” he asked.

“Not at home,” repeated Blotson.
