years, but it's all over now. I suggest you keep your heads and resist the temptation to make matters worse than they are." "Miss Meuhl," Fith said, "a peace squad waits outside your consulate. It is clear you are in the hands of a dangerous lunatic. As always, the "Don't bother," Retief said. "You know what was in those files I looked over this morning." Retief turned at a sound behind him. Miss Meuhl was at the door, reaching for the safe-lock release.... "Don't!" Retief jumped—too late. The door burst inward. A crowd of crested Groaci pressed into the room, pushed Miss Meuhl back, aimed scatter guns at Retief. Police Chief Shluh pushed forward. "You can't turn this invitation down," Administrative Assistant Meuhl said flatly. "I'll make that 'accepts with pleasure'." Retief exhaled a plume of cigar smoke. "Attempt no violence, Terrestrial," he said. "I cannot promise to "I suggest you move back out the same way you came in." "I invited them here," Miss Meuhl spoke up. "They are here at my "You can't offend the Groaci," Miss Meuhl said sharply. "Consul Whaffle "Never mind the excuses," Retief said. "Just tell him I won't be there." He stood up. best if we removed this deranged person to a place of safety?" "You're making a serious mistake, Shluh," Retief said. "Yes," Miss Meuhl said. "You're quite right, Mr. Shluh. Please escort Mr. Retief to his quarters in this building—" "I don't advise you to violate my diplomatic immunity, Fith," Retief said. "As chief of mission," Miss Meuhl said quickly, "I hereby waive immunity in the case of Mr. Retief." Shluh produced a hand recorder. "Kindly repeat your statement, Madam, "Are you leaving the office?" Miss Meuhl adjusted her glasses. "I have some important letters here for your signature." "I don't recall dictating any letters today, Miss Meuhl," Retief said, pulling on a light cape. "Since I'm cutting out the culture from now on," Retief said, "I won't be so busy." Retief looked thoughtfully at Miss Meuhl. "You've been here on Groac "Well!" Miss Meuhl said. "May I ask where you'll be if something comes up?" "I'm going over to the Foreign Office Archives." "Certainly not on Groac." Retief nodded. "Thanks, Miss Meuhl," he said. "I'll be back before you close the office." Miss Meuhl's face was set in lines of grim disapproval as he closed the door. At the office, Miss Meuhl would be waiting with another list of complaints. Retief studied the carving over the open doorways along the street. II "There you are!" Miss Meuhl said, eyeing Retief over her lenses. "There are two gentlemen waiting to see you. Groacian gentlemen." "Government men, I imagine. Word travels fast." Retief pulled off his indicative of rank rose as Retief entered the room. Neither offered a courteous snap of the mandibles, Retief noted. They were mad, all right. "I am Fith, of the Terrestrial Desk, Ministry of Foreign Affairs, Mr. Shluh, of the Internal Police?" "Sit down, gentlemen," Retief said. They resumed their seats. Miss Meuhl hovered nervously, then sat on the edge of a comfortless chair. "Just keep that recorder going," Retief snapped. "I'll not be a party—" "You'll do as you're told, Miss Meuhl," Retief said quietly. "I'm telling you to make an official sealed record of this conversation." Miss Meuhl sat down. Retief turned a steady look on Miss Meuhl. She closed her mouth. The Groaci sat down. "We wish to show our contrition," Fith said. "We will show you the ship." "Miss Meuhl," Retief said. "If I don't come back in a reasonable length of time, transmit that recording to Regional Headquarters, sealed." He the rhythmic puffing of the motor and said nothing. III "Miss Meuhl," Retief said, "I want you to listen carefully to what I'm "I'm sure I don't know what you're talking about," Miss Meuhl snapped, indignation. "You're like a ... a...." "You and I are in a tight spot, Miss Meuhl. The logical next move for door. "I'll be back in a couple of hours," he said. Miss Meuhl stared after safe-lock and stepped into the darkened consular office. He looked tired. Miss Meuhl, dozing in a chair, awoke with a start. She looked at Retief, rose and snapped on a light, turned to stare. "What in the world—Where have you been? What's happened to your "I got a little dirty. Don't worry about it." Retief went to his desk, opened a drawer and replaced the needler. "Where have you been?" Miss Meuhl demanded. "I stayed here—" have a long transmission for Regional Headquarters." "Are you going to tell me where you've been?" "I have a message to get off first, Miss Meuhl," Retief said sharply. "I've been to the Foreign Ministry," he added. "I'll tell you all about it later." "This is absolutely the end!" Miss Meuhl said. "Thank heaven I've already—" "Get that sender going, woman!" Retief snapped. "This is important." "I've already done so, Mr. Retief!" Miss Meuhl said harshly. "I've been waiting for you to come back here...." She turned to the communicator, image appeared. "He's here now," Miss Meuhl said to the screen. She looked at Retief triumphantly. "I have done my duty, Mr. Retief," Miss Meuhl said. "I made a full report to Regional Headquarters last night, as soon as you left this office. Any doubts I may have had as to the rightness of that decision have been completely dispelled by what you've just told me." Retief looked at her levelly. "You've been a busy girl, Miss Meuhl. Did "Mr. Retief," the face on the screen said, "I am Counsellor Pardy, DSO-1, Deputy Under-secretary for the region. I have received a report on your conduct which makes it mandatory for me to relieve you administratively, vice Miss Yolanda Meuhl, DAO-9. Pending the findings of a Board of Inquiry, you will—" ignore. I can't afford that, at this moment. Listen, Miss Meuhl," Retief went on earnestly, "I've found the missing cruiser." "You heard him relieve you!" to, Miss Meuhl. But until I've heard and acknowledged a verbal order, it has no force. If I'm wrong, he'll get my resignation. If I'm right, that suspension would be embarrassing all around." "You're defying lawful authority! I'm in charge here now." Miss Meuhl stepped to the local communicator. "I'm going to report this terrible thing to the Groaci at once, and transmission to Headquarters, along with a call for an armed task force. Then we'll settle down to wait." Retief ignored Miss Meuhl's fury as he spoke into the recorder. The local communicator chimed. Miss Meuhl jumped up, staring at it. "Go ahead," Retief said. "Answer it."
