36 HALO: FIRST STRIKE
"That's highly un—" Cortana froze for a split second. The static
around her vanished, and she stared off into space. "Interesting."
"What?"
Cortana looked distracted, then seemed to snap out of it.
"New data. That signal echo's getting stronger."
"Meaning?"
"Meaning," she replied, "it's not an echo."
The scanner panel hummed back to life as Cortana activated
the Longsword's long-range detection gear. "Uh-oh," she said, a
moment later.

runtime to the task. I'm building a multiplex filtering algorithm.
Customizing the current shape-signature recognition software."
Another ship rounded the horizon of Basis. It was larger than
any Covenant ship the Master Chief had seen. It had the sleek
three-bulbed shape of one of their destroyers, but it must have
