Free A Cold Heart by Jonathan Kellerman

Hamelin when you need him-so... where was I... oh, yes, I opened the door and had a look out back and there were no rats. But there was a woman. Foraging in the Dumpster. Obviously homeless, obviously quite mad.'
     
     
'Mad as in angry?' said Milo.
     
     
'Mad as in disturbed, psychotic, mentally ill. I abhor labels, but sometimes they do get the picture across. This one was mad as the proverbial chapeau maker.'
     
     
'You could tell this by-'
     
     
'Her eyes, for starts,' said Barnes. 'Wild eyes - scared eyes. Jumping all over the place.' She tried to demonstrate with her own gray orbs, but they moved lazily. Blinking several times, as if to clear them, she turned to Lance and scratched behind his ear, and said, 'Easy now, you're a good boy... then there was the way she carried herself, her clothes - mismatched, oversized, too many layers for the weather. I've lived in Venice for fifty-three years, Detective. I've seen enough mental illness to know it when it stares me in the face. Then, of course, there was the foraging. The moment the door opened she jumped back, lost her balance, and nearly fell. Such fear. I said, "If you wait right here, I'll fetch you something to eat." But she raised her hand to her mouth, chewed her knuckles, and ran off. They do that a lot, you know. Turn down food. Some of them even get hostile when you try to help them. They've got voices blabbering in their heads, telling them who-knows-what. Can you blame them for not trusting?'
     
     
She ruffled the dog some more. 'It's probably nothing, but in view of what happened to Julie I don't suppose we can be too complacent.'
     
     
'No we can't, ma'am. What else can you tell me about this woman?' said Milo.
     
     
The old woman's eyes sparked. 'So you do think it's important?'
     
     
'At this stage, everything's important. I appreciate your telling me.'
     
     
'Well, that's good to know. Because I almost didn't tell you, being as it was a woman and my assumption was a man killed Julie - the way she was...' The old woman's eyes clamped shut, then fluttered open. 'I'm still trying to rid myself of the image... not that this woman couldn't have overpowered Julie. She was large - maybe six feet tall. Built big, too. Though with all that clothing, it was hard to tell, precisely. And we were only face-to-face for a second or so.'
     
     
'Big bones,' said Milo.
     
     
'Sturdy - almost masculine.'
     
     
'Could it have been a man dressed up as a-'
     
     
Barnes laughed. 'No, no, this one was pure girl all right. But a big girl. A lot bigger than Julie. Which got
     
     
me thinking. It needn't have been a man at all, right? Especially if we're dealing with someone not in their right mind.'
     
     
Milo's pad was out. 'How old would you say she was?'
     
     
'I'd guess thirties, but it's a guess because that kind of misery - homelessness, mental illness - it overrides age, doesn't it?'
     
     
'In what way, ma'am?'
     
     
'What I mean,' said Barnes, 'is that people like that oil look ancient and damaged - there's a coating of despair. This one, though, she'd managed to hold on to some of her youth; under the grime I could see some youth. I can't explain it any better than that.'
     
     
CoCo Barnes ticked a finger. 'In terms of other details, she wore a thick, padded military-type camouflage jacket over a red, black, and white flannel shirt over a blue UCLA sweatshirt. UCLA in white letters, the C was half-gone. On the bottom were heavy-duty gray sweatpants, and from the way they bulked, she had on at least one other pair of pants underneath. White, lace-up tennis shoes on her feet and a broad-brimmed black straw hat atop her head. The brim was shredded in front - pieces of straw poking out. Her hair was bunched up in the hat, but some had come loose, and it was red. And curly. Curly red hair. Add a layer of grime to all of that, and you've got the picture.'
     
     
Milo scribbled. 'Ever see her before?'
     
     
'No,' said Barnes. 'Not on the
