nine o'clock in the evening
Of course the orders will be different at different posts , but these you will receive from the officials of the chamberlain . You will be on duty , as I learn , for six hours each day , and will for the rest of the time be free to go where you please . I suppose by this time all of you have learned sufficient Latin to converse freely . Remember that at nine o'clock in the evening you must all be in the palace . Phaon has arranged for an apartment that you will occupy together . There you will keep your arms , and be always ready , when you receive a message from me , to attend prepared for fighting . There is one thing more : do not mingle with the Romans more than you can help ; listen to no tales relating to the emperor , and let no man discuss with you any question of state .
