ten o’clock
` I trust I shall have the pleasure of seeing you and your friend at my rooms , and of spending a pleasant evening with you , after this awkward mistake , ' said the little doctor ; ` are you disengaged this evening ? ' ` We have some friends here , ' replied Mr. Winkle , ` and I should not like to leave them to-night . Perhaps you and your friend will join us at the Bull . ' ` With great pleasure , ' said the little doctor ; ` will ten o'clock be too late to look in for half an hour ? ' ` Oh dear , no , ' said Mr. Winkle . ` I shall be most happy to introduce you to my friends , Mr. Pickwick and Mr. Tupman . ' ` It will give me great pleasure , I am sure , ' replied Doctor Slammer , little suspecting who Mr. Tupman was .
