The old man touched his hat, looked sharply towards Hewitt, who was waiting near the rectory door, and then disappeared round a corner of the house, the rector following. In a few seconds Mr. Potswood reappeared, with a slip of paper in his hand. "Here," he said, "see this! The old man was told to give it to nobody but me, and in nobody else's presence. He's been waiting since one o'clock."
Scrawled on the paper, in trembling and straggling letters, were these words:—
"You must not bring Mr. Martin Hewitt to my house this afternoon. I am watched. It is hopeless. Do not desert me. Bring him to-night after dark at eight. I shall want his best skill, and you shall know all. After dark. Come to the back gate in the lane, which will be ajar, and through the conservatory at the side, where my niece will be waiting at eight, after dark. Burn this and do not let it out of your sight first. Send a line by this man to say you will do as I ask, but do not say what it is, for fear of accidents. Send at once. Do come at eight, with Mr. Hewitt."
"We must do as he says," remarked Hewitt. "We know nothing of this matter, and we must be guided till we do. Just write an unsigned note—'All shall be as you request,' or words to that effect, and be sure the man gives it to him. Let him out behind through the churchyard, if possible, and tell him not to go straight from one house to the other. Is he an intelligent man?"
"Yes—uncommonly shrewd, I believe. He says he can't have been followed. He knows several gardeners hereabout, and he seems to have called on each of them on his way—in at the front of the garden and out at the back each time, after a few minutes' conversation. Gipps is rather a cunning old fellow."
"Ah," said Hewitt admiringly, "that's the sort of messenger I often want. I'll give him half a crown for himself and the money to pay for a telegram on his way. He knows nothing essential, of course?"
"No—only that his master is in some sort of trouble, and warned him that he might be followed."
"That is good. I shall telegraph to Detective-Inspector Plummer, of Scotland Yard. All right—I quite understand that all I have heard is confidential. I shall tell Plummer nothing till I may—indeed, as yet I have very little to tell that would help him. But I think it will be well to have the police within call—we may want them at a moment's notice; I have no police powers, you see, and Plummer has the Denson case in hand. I will ask him to be here, at this house, before a quarter to eight, if you will allow me."
And so the telegram went to Plummer, and Hewitt, accepting the rector's invitation to an early dinner before starting on their visit, resigned himself to wait. He did not like the waste of time, as he frankly told Mr. Potswood. He would have preferred to see Mason at once, at any risk, and to take what means he thought necessary without delay. But as it seemed that the risk was to be chiefly Mason's, and as Mason knew all of which both he and the rector were ignorant, Mason must be allowed to choose his own time.
The excellent Mr. Potswood endured agonies of suspense, though he also insisted that Mason's wishes must be observed exactly. "What is it all—what can it be?" he ejaculated again and again. "What dreadful influence can thus compass a man about, here in London, in these times?"
