'I'll chance that,' declared David at once. 'I should rather enjoy the experience, not that I am anxious to be a thief taker. Still, I am in your employ and will obey whatever orders are given me.'
'Certainly: I shall obey your orders seeing that I am in your service.'
'But you could decline to take this risk if you wished. However, we have considered the matter. There will be a salary of a pound a night while you are watchman, and a liberal reward if the offender is apprehended. Now I want you to finish your work, and join me at the police station. Don't let other employees see you going there. We will make our final arrangements with the officials of the police.'
It may be imagined that David was somewhat excited after such an announcement. Not for one moment did he think of declining the task required of him; for he looked upon it as a duty. He obtained good wages, these people had been kind to him, and if he could serve them, all the better. Besides, it might lead to a better and more highly-paid post. He polished the brass of his lift, put aside his livery, and emerged from the building, leaving one of the officials to close the establishment. Then, taking a side street, he hurried to the police station. Once there the final arrangements were soon made. The manager already knew that David was lodging with a policeman, and to our hero's pleasure he learned that Constable Hemming was to take duty outside the store, being relieved by a friend. Both were to be provided with keys, while David was presented with a basket containing food and drink. An electric torch was handed to him, as well as a life preserver and a whistle. Thus equipped he drove back to the establishment at ten that night, and slipped cautiously into the store.
Just keep moving and doing things all the while,' Hemming advised him. 'Lights are always kept going on all the floors, so that you'll have no difficulty in seeing. But it's wonderful how sleepy a fellow gets, especially when he's done the job on more than one occasion. Keep moving is the thing. Always remember to walk softly. If you spot anything funny, keep quiet, and come along to warn me. The end of a stick pushed through the letter-box will tell me I'm wanted. Don't get scared. It's only fools and babies as fly from their own shadows.'
