She was at this time bordering upon a state of collapse. Insomnia, which latterly had defied dangerously increased doses of veronal, was telling upon nerve and brain. Now, her head aching so that she often wondered how long she could retain sanity, she found herself deprived not only of cocaine, but also of malourea. Margaret Halley was her last hope, and to Margaret she hastened on the day before the tragedy which was destined to bring to light the sinister operations of the Kazmah group. Although, perhaps mercifully, she was unaware of the fact, representatives of Spinker’s Agency had been following her during the whole of the preceding fortnight. That Rita was in desperate trouble of some kind her husband had not failed to perceive, and her reticence had quite naturally led him to a certain conclusion. He had sought to win her confidence by every conceivable means and had failed. At last had come doubt—and the hateful interview with Spinker. As Rita turned in at the doorway below Margaret’s flat, then, Brisley was lighting a cigarette in the shelter of a porch nearly opposite, and Gunn was not far away. Margaret immediately perceived that her friend’s condition was alarming. But she realized that whatever the cause to which it might be due, it gave her the opportunity for which she had been waiting. She wrote a prescription containing one grain of cocaine, but declined firmly to issue others unless Rita authorized her, in writing, to undertake a cure of the drug habit. Rita’s disjointed statements pointed to a conspiracy of some kind on the part of those who had been supplying her with drugs, but Margaret knew from experience that to exhibit curiosity in regard to the matter would be merely to provoke evasions. A hopeless day and a pain-racked, sleepless night found Kazmah’s unhappy victim in the mood for any measure, however desperate, which should promise even temporary relief. Monte Irvin went out very early, and at about eleven o’clock Rita rang up Kazmah’s, but only to be informed by Rashîd, who replied, that Kazmah was still away. “This evening he tell me that he see your friend if he come, my lady.” As if the Fates sought to test her endurance to the utmost, Quentin Gray called shortly afterwards and invited her to dine with him and go to a theatre that evening. For five age-long seconds Rita hesitated. If no plan offered itself by nightfall she knew that her last scruple would be conquered. “After all,” whispered a voice within her brain, “Quentin is a man. Even if I took him to Kazmah’s and he was in some way induced to try opium, or even cocaine, he would probably never become addicted to drug-taking. But I should have done my part—” “Very well, Quentin,” she heard herself saying aloud. “Will you call for me?”
