nine
o'clock
About ten o'clock , when the two boys had been gone about an hour , Mr. William began to miss his brother , and to wonder where he had gone . So he rang the bell , and his courier came into the room . `` Pacifico , '' said Mr. William , `` do you know where Copley is ? '' `` No , sir , '' said Pacifico ; `` I did not see him from since it was nine o'clock . '' `` Go down below , '' said Mr. William , `` and inquire of the concierge and the porters if they have seen him , or know where he is . '' Mr. William followed Pacifico as he went out , in order to speak a moment to a friend of his who occupied the next apartment . As he came back he met Pacifico at the head of the stairs , and received his answer there .
