`` My dear sir , do you suppose that I thought of taking _ you _ with us ? No , Mr. Hardcastle , the risks of this sort of enterprise are for those who are paid to run them . And there is a risk ; if we timed our attack too early or too late there would be bloodshed to a certainty . But at two o'clock the average man is fast asleep ; at a quarter after one , therefore , I start with Sergeant Cameron and Constable Tyler . '' Hardcastle yawned again . `` I should like to have been with you , but there are compensations , '' said he . `` I doubt if I shall even stay up to see you off . ''
