"Stood out to their dog. One of those attentive retrievers. They were ready to walk right past the van but the dog kept nosing around, barking, wouldn't leave it alone. Finally, they had a look inside. So much for walking for health, huh? That kind of thing could put you off exercise for a long time."

"Bad?"

"Not what I'd want as an aerobic stimulant. Dr. Mate was trussed up to his own machine."

"The Humanitron," I said. Mate's label for his death apparatus. Silent passage for Happy Travelers.

Milo's smile was crooked, hard to read. "You hear about that thing, all the people he used it on, you expect it to be some high-tech gizmo. It's a piece of junk, Alex. Looks like a loser in a junior-high science fair. Mismatched screws, all wobbly. Like Mate cobbled it from spare parts."

"It worked," I said.

"Oh yeah. It worked fine. Fifty times. Which is a good place to start, right? Fifty families. Maybe someone didn't approve of Mate's brand of travel agency. Potentially, we're talking hundreds of suspects. Problem one is we've been having a hard time reaching them. Seems lots of Mate's chosen were from out-of-state— good luck locating the survivors. The department's lent me two brand-new Detective-I's to do phone work and other scut. So far people don't want to talk to them about old Eldon, and the few who do think the guy was a saint— 'Grandma's doctors watched her writhe in agony and wouldn't do a damn thing. Dr. Mate was the only one willing to help.' Alibi-talk or true belief? I'd need face-to-faces with all of them, maybe you there to psychoanalyze, and so far it's been telephonic. We're making our way through the list."

"Trussed to the machine," I said. "What makes you think homicide? Maybe it was voluntary. Mate decided it was his own time to skid off the mortal coil, and practiced what he preached."

"Wait, there's more. He was hooked up, all right— I.V. in each arm, one bottle full of the tranquilizer he uses— thiopental— the other with the potassium chloride for the heart attack. And his thumb was touching this little trip-wire doohickey that gets the flow going. Coroner said the potassium had kicked in for at least a few minutes, so Mate would've been dead from that, if he wasn't dead already. But he was. The gizmo was all for show, Alex. What dispatched him was no mercy killing: he got slammed on the head hard enough to crack his skull and cause a subdural hematoma, then someone cut him up, none too neatly. 'Ensanguination due to extensive genital mutilation.' "

"He was castrated?" I said.
