It's a miracle I don't weigh three hundred pounds with all the sitting around I have to do. Once I followed Donner on his morning drive into work, all I could do was sit in my car.

Waiting until he went somewhere else.

My only problem was that he didn't. He never left his office until it was time for him to go home. At this rate, the case was going to go on for a very long time.

I had been hoping for some kind of a break. Hoping Donner would have some meeting with his mystery partner. At the very least, get a phone call from this mystery person.

Now as I followed him back home, all I had to look forward to was another long night sitting in front of his house.

Again I was hoping for some luck. Maybe contact would be made at his home.

Those hopes were dashed the instant Donner picked up his phone.

One of the toys I have for surveillance is a small box which ties in with my wire tap set. A great thing it does is tell you the number of the phone at the other end of the line.

Even as he dialed, it hit me that I knew what this number was.

He was calling the Agency again.

I'm not even sure why I did it, but my hand quickly reached for the little black box.

There was one other thing my toy could do.

By flicking a switch, I could cut in and take over the call.

"Agency," I said in a dull voice, chomping my lips as if chewing gum.

"This is Mr. Donner. I believe you know what I want."

I played my end of the conversation just the way the operator had done the night before, assuring him someone would be sent right out.

Once I hung up I looked at my watch. Thirty minutes would be tight, but I thought I could make it to my place to change, and still get back in time.

Questions filled my mind as I drove. I still didn't know why I had done it. Why I suddenly felt the need to take the place of a call girl.
