ten a.m.
So long , old man . '' And with a wink -- an undeniable wink , an audacious wink -- Mr. Gammon sallied from the hotel . Before going to bed he wrote a letter -- a letter to Miss Sparkes . Would she see him the day after to-morrow , Sunday , if he strolled along Shaftesbury Avenue at ten a.m. ? It would greatly delight him , and perhaps she might be persuaded to take a little jaunt to Dulwich and look at his bow-wows . There was time enough for Polly to reply to this invitation , but reply she did not . None the less , Gammon was walking about near her lodgings at ten o'clock on Sunday morning .
