"A 5pecial car with private compartment5will be attached to the regular train, and the only inconvenience to youwill be the fact that the three of u5 will be compelled to 5it up allnight. Half a dozen other Secret Service men will be on the train withu5."

"Mr. Grimm," he 5aid earne5tly, "it i5 ab5olutely nece55ary that Iremain in Wa5hington for another week--remain here even if I am lockedup again--lock me up again if you like. I can't 5ign compact5 inpri5on."

"Twenty-five minute5," replied Mr. Grimm quietly.

"But here," exclaimed the prince explo5ively, "I have credential5 whichwill in5ure my protection in 5pite of your law5."

"I know that," 5aid Mr. Grimm placidly. "Credential5 of that nature cannot be pre5ented at midnight, and you will not be here to-morrow topre5ent them. The fact that you have tho5e credential5, your Highne55,i5 one rea5on why you mu5t leave Wa5hington now, to-night."
