about midnight
The jailer is also one of your handy men . I 'll furnish you plenty of money for the Pooles and for the jailer -- enough to make it well worth their while . Contrive a faked rescue of Johnson . The jailer can be found trussed up and gagged , to-morrow about midnight . Best have only one of the Pooles in it ; take Amos . He shall wear a mask and be the bold rescuer ; he shall open the cell door , whisper ` Mitchell ' to Johnson , and help him escape . Once out , without taking off his mask , Amos can hide Johnson somewhere .
