That night men from Watford kept a watch upon the house, but there was no disturbance. Her watchers had evidently taken the alarm. But it was in no very certain or very happy state that Doris drove her machine out of the gate of the Park in the later afternoon of the next day with her cousin Tom beside her and Wilson and the luggage in the rear seat. The main road to London was empty of vehicles except for a man on a motor-cycle just ahead of her bound in the same direction. At least, she was no longer to be watched. There was plenty of time, so she drove leisurely, reaching Euston Station with twenty minutes to spare. She sent a wire to Lady Heathcote and then Tom saw her safely into her carriage. The movement of the train soothed her and she closed her eyes and slept, Wilson like a watchful Gorgon, guarding against intrusion. There was but one incident which destroyed the peace of the journey. Toward morning, Wilson, who slept with one eye open, wakened her suddenly and asked her quietly to look out of the window. Her train had stopped at a large station, the platform of which was well lighted. From the darkness of their compartment she followed the direction of Wilson’s figure. Outside, pacing the platform and smoking cigarettes, were two men. “What is it?” asked Doris, half asleep. “The big one,” whispered Wilson excitedly. “It was him that was ridin’ the motor-cycle.” Doris remembered passing and repassing the vehicle on the road to London, and the face of its driver came back to her. She peered out at him eagerly and as the man turned she saw the face and figure of the larger man clearly. It was the motor-cycle man, and in a rush the thought came to her that his figure and bearing were strangely familiar. “It’s true,” she whispered, her fingers on Wilson’s arm. “We’re followed. It’s the same man. Last night, too.” “Last night?” “Yes. It’s the man called Jim, who searched Mr. Hammersley in the road.” “No,” said Wilson, her eyes brightening. “You don’t say so, Miss Mather. Of all the brazen----” “Sh--” said Doris. But there was no more sleep for either of them that night. Bolt upright, side by side, they watched the dawn grow into sunrise and the sunrise into broad day. They saw no more of the motor-cycle man and Doris reassured herself that there was nothing to be feared now that the packet was-- She started in affright. The packet at Betty Heathcote’s! Perhaps at this very moment lying innocently in Betty’s post-box or in the careless hands of some stupid Scotch gardener, or worse yet inviting curiosity on Betty’s desk or library table. Her heart sank within her as she realized that her brave plans might yet miscarry.
