It was time for me to make one more of my anonymous phone calls.

I know who made that anonymous phone call last night.

Later, he gets an anonymous call asking how his training went.

We're going to leave her just as she is in the kitchen and make an anonymous call.

He wanted to know why Jack hadn't said anything about his own anonymous calls.

"Why didn't you tell us about the anonymous phone call earlier?"

"We got an anonymous call, maybe from the driver himself, who might not have been sure the girl was dead."

The only thing to do would be to give the cops an anonymous call and ask them to come out.

Police learned of the incident from an anonymous 911 call.

"I've had anonymous phone calls asking which one I am."
