midnight
`` In your stead , general ? '' `` Yes . He will do nothing all day , expecting me to accept him on my side at night . At midnight you will go to him , and say that I have such a bad headache I have had to go to bed , but that I will be with him at seven o'clock in the morning without fail . He will believe you , or he wo n't believe you ; but at any rate it will be too late for him to act against us . By seven in the morning I shall have ten thousand men under my command . '' `` Very good , general .
