But a change had come about in the relations between the three doctors, and in every way the change was for the better. If Jack Alvarez was not exactly cordial to Dal Timgar, at least he had dropped the open antagonism that he had shown before. Apparently Tiger's angry outburst had startled Jack, as though he had never really considered that the big Earthman might honestly be attached to his friend from Garv II, and the Blue Doctor seemed sincere in his agreement to work with Dal and Tiger as a team. But bit by bit Dal could sense that the change in Jack's attitude went deeper than the surface. "You know, I really think he was _scared_ of me," Dal said one night when he and Tiger were alone. "Sounds silly, but I think it's true. He pretends to be so sure of himself, but I think he's as worried about doing things wrong as we are, and just won't admit it. And he really thought I was a threat when I came aboard." "He probably had a good thorough briefing from Black Doctor Tanner before he got the assignment," Tiger said grimly. "Maybe--but somehow I don't think he cares for the Black Doctor much more than we do." But whatever the reason, much of the tension was gone when the _Lancet_ had left the Moruan system behind. A great weight seemed to have been lifted, and if there was not quite peace on board, at least there was an uneasy truce. Tiger and Jack were almost friendly, talking together more often and getting to know each other better. Jack still avoided Dal and seldom included him in conversations, but the open contempt of the first few weeks on the ship now seemed tempered somewhat. Once again the _Lancet_'s calls fell into a pattern. Landings on the outpost planets became routine, bright spots in a lonely and wandering existence. The calls that came in represented few real problems. The ship stopped at one contract planet to organize a mass inoculation program against a parasitic infestation resembling malaria. They paused at another place to teach the native doctors the use of some new surgical instruments that had been developed in Hospital Earth laboratories just for them. Frantic emergency calls usually proved to involve trivial problems, but once or twice potentially serious situations were spotted early, before they could develop into real trouble. And as the three doctors got used to the responsibilities of a patrol ship's rounds, and grew more confident of their ability to handle the problems thrust upon them, they found themselves working more and more efficiently as a team.
