seven o’clock
`` I do n't imagine that you 'll propose that you and I , for our amusement , shall drive about London in a hansom . '' `` There 's no reason we should n't stay here -- if you do n't dislike it . It 's very warm ; there will be half an hour yet before dark ; and if you permit it I 'll light a cigarette . '' `` You may do what you please , '' said Isabel , `` if you 'll amuse me till seven o'clock . I propose at that hour to go back and partake of a simple and solitary repast -- two poached eggs and a muffin -- at Pratt 's Hotel . '' `` May n't I dine with you ? '' Ralph asked .
