four o’clock
`` Lord Donal 's description fits the Princess exactly , and yet I never thought of her before . '' Jennie hurried away from the detective 's office , happy in the belief that she had not betrayed herself , although she was not blind to the fact that her escape was due more to good luck than to any presence of mind of her own , which had nearly deserted her at one or two points in the conversation . When Mr. Hardwick saw her , he asked how much space he should have to reserve for the romance in high life ; but she told him there was nothing in the case , so far as she could see , to interest any sane reader . Here matters rested for a fortnight ; then the girl received an urgent note from Cadbury Taylor , asking her to call at his office next day promptly at four o'clock . It was very important , he said , and he hoped she would on no account disappoint him . Jennie 's first impulse was not to go , but she was so anxious to learn what progress the detective had made in the case , fearing that at last he might have got on the right track , that she felt it would be unwise to take the risk of not seeing him . If his suspicions were really aroused , her absence might possibly serve to confirm them .
