six o’clock
The man who entered was a sturdy , middle-sized fellow , some thirty years of age , clean-shaven , and sallow-skinned , with a bland , insinuating manner , and a pair of wonderfully sharp and penetrating grey eyes . He shot a questioning glance at each of us , placed his shiny top-hat upon the sideboard , and with a slight bow sidled down into the nearest chair . `` Good-evening , Mr. James Windibank , '' said Holmes . `` I think that this typewritten letter is from you , in which you made an appointment with me for six o'clock ? '' `` Yes , sir . I am afraid that I am a little late , but I am not quite my own master , you know . I am sorry that Miss Sutherland has troubled you about this little matter , for I think it is far better not to wash linen of the sort in public .
