“No news of Mrs Saxton, I suppose?” asked Sheila, as Smeaton was on the point of leaving the drawing-room.
“None at all. She is at home, and nobody seems to go near her but her brother. I told you how she put me on the wrong scent about Stent. Once or twice I have thought of going there again and taxing her with it. But what would be the good? She would still stick to her story that she knew next to nothing about him. In giving me the St. Albans clue she would swear she had mixed him up with somebody else. My men seem cooling their heels to no purpose. She knows she is being watched, and she won’t give us a chance. I expect she does all her necessary work on the telephone, and we must attend to that point at once.”
Next morning Mrs Saxton aroused herself from her apparent inactivity, and gave her watchers a big surprise, which added to Smeaton’s growing dissatisfaction with the state of affairs.
At about eleven o’clock her maid whistled up a taxi. Mason, the head detective on duty, immediately communicated with his own taxi-driver, waiting in readiness round the corner, and entered the cab, giving instructions to follow the other when it started.
She came out without any luggage, simply carrying a small vanity bag. She might be going shopping, to pay a visit, to send a telegram, or a hundred-and-one things. His duty was to follow her.
The woman’s cab drove down the Edgware Road, crossed the Park, and stopped at the Hyde Park Tube Station. Here Mrs Saxton paid the fare, and went into the booking-office. Mason at her heels. She took a ticket to Piccadilly Circus, and Mason did the same. They went down together in the same lift, Mrs Saxton near the door of exit, he at the other end of the lift.
He was puzzled as to her movements. If she wanted to get to Piccadilly Circus, why had she taken this roundabout route? The taxi would have taken her there direct.
The train was full. For a few seconds he was separated from her by a surging and struggling crowd blocking the entrances to the long cars. By dint of hard fighting he managed to get in the same carriage.
So far, luck seemed in his favour. It was a non-stop train, and went past Down Street. At the next station, Dover Street, he saw her turn half round, and cast a furtive glance in his direction. She was evidently debating within herself if she would chance getting out there.
While thus deliberating, the train re-started. At Piccadilly Circus there was a considerable exodus, as there always is. The process of disembarking was slow, owing to the number of passengers.
