Identifies smell

I looked up at her. Then, moving deliberately, I opened the manila envelope Vince had given me.
"What's that?" she asked.
"Surveillance photos," I said quietly. "Shot through a telephoto lens from a block away."
She blinked at me. "What?"
"I hired Vince to take some pictures," I said. "Well, technically Murphy hired him, because I was worried about my phone being bugged. But I'm getting the bill, so really, it was me."
"Pictures? What pictures?"
"Of the Way to Chicago from Edinburgh," I said. "Where it opens up into that alley behind the old meatpacking factory. I had Vince take pictures of anyone coming out of it, right after I informed Edinburgh about the meeting on the island."

Everyone on the Senior Council except Ebenezar and, for some reason, the Gatekeeper, turned to stare slack-jawed at Peabody.
The Senior Council's secretary sat perfectly still beneath his little lap desk. Then he said, "I take it that you have proof more convincing than a simple visual image? Such things are easily manufactured."
"In fact," I said, "I do. I had a witness who was close enough to smell you."
On cue, Mouse stood up and turned toward Peabody.
His low growl filled the room like a big, gentle drumroll.
"That's all you have?" Peabody asked. "A photo? And a dog?"
Mai looked as if someone had hit her between the eyes with a sledgehammer. "That," she said, in a breathless tone, "is a Foo dog." She stared at me. "Where did you get such a thing? And why were you allowed to keep it?"
"He sort of picked me," I said.
The Merlin's eyes had brightened. "Mai. The beast's identification is reliable?"
She stared at me in obvious confusion. "Entirely. There are several other wizards present who could testify to the fact."
"Yes," rumbled a stocky, bald man with an Asian cast to his features.
"It's true," said a middle-aged woman, with skin several tones darker than my own, maybe from India or Pakistan.
"Interesting," the Merlin said, turning toward Peabody. There was something almost sharklike about his sudden focus.
