Children of the Lens by E.E. Smith

Second-Stage Lensman Tregonsee of Rigel IV did not rush madly out into space in quest of something or anything Boskonian in response to Kinnison's call. To hurry was not Tregonsee's way. He could move fast upon occasion, but before he would move at all he had to know exactly how, where, and why he should move.

He conferred with his three fellows, he furnished them with all the data he possessed, he helped integrate the totaled facts into one composite. That composite pleased the others well enough so that they went to work, each in his own fashion, but it did not please Tregonsee. He could not visualize any coherent whole from the available parts. Therefore, while Kinnison was investigating the fall of Antigan IV, Tregonsee was sitting -- or rather, standing -- still and thinking. He was still standing still and thinking when Kinnison went to Radelix.
