When Aly got back into the house, she locked the door and then shuffled up the stairs. On the wall that led up to her room were various projects...some of her favorite paintings dating back from the earliest days of her education, various academic certificates she'd won, from the time she was a young child to the congratulatory note she'd found on her desk the day she'd solved her hundredth case.
She hadn't put up any of them, it was all the Chief's doing. They were so routine to her that she rarely saw them, but tonight she paused and looked at them. It was so weird; the man used his own awards, more solid awards for valor in service, for paperweights or other ridiculous, mundane uses. But that tacky purple and orange painting she'd done at fifteen that vaguely resembled a house was still in the same place it had been for the last seventy years. It was crumbling with age, but still there.
She had to shake her head. She doubted that even her biological father, had he stuck around to raise her, could have been nearly as proud of her as the Chief, even for things that didn't really deserve pride.
Like today's failure.
Frustrated, Aly reached out, taking the old painting and crumbling it, tossing it down the stairs. How could she miss the clues? There had to be clues just glaring to be noticed, begging to take a worthy investigator right to the kidnapper and his victim.
In her room, Aly kicked off her boots, tossed her hat aside, and then threw her coat at the foot of her bed, flopping down on the mattress and glaring up at the ceiling. How could she be incompetent enough to doom a child to death?
A jumble of lights on her ceiling caught her eye; her suncatcher was throwing purple and blue specters of the light it stole from the streetlamps. When the lamps had first been installed for the benefit of the humans who did business with the technologically advanced nation, they'd annoyed Alydia to no end. How was she supposed to sleep with all the light? But eventually the panorama of shadows it sent scurrying across her room had become entertaining, and then soothing. And the light cast off of the delicate piece of glass in the window had always comforted her, no matter what.
Except tonight.
There's got to be something...in his pattern...
Suddenly a burst of inspiration struck her in the form of the shards of light dancing on her ceiling, and Aly sat up straight. There had been something in common in all of the areas, something so minor and mundane that she and Aonar had automatically dismissed it. But what was it?
She thought back to her conversations with her partner over the course of the day, and remembered one particularly annoying tendency her partner displayed. He made sure to step on every single sewer grate.
That's it. The sewer has access to all those areas, and to the river. It's how he remained unseen.
Hopping up, Aly hurried to put on her coat, hat, and boots, scribbled a quick note for the Chief, then grabbed her whip off the side table and was gone into the night.
