"I'll see who it is," Tom said, and hurried to the door, feeling a twinge of apprehension.

Was this a new attempt by Brungarian agents?

It was Harlan Ames!

"Hi, Harlan!" Tom opened the door before Ames had a chance to ring the doorbell. "We heard you coming!"

The security chief was startled when he realized he had activated the alarm system.

"That's strange," he said uneasily. "Tom, I wonder if—"

He broke off to dart a quick glance at his wrist. Then his face relaxed into a look of chagrin.

"Great! I forgot my wrist watch!" he murmured. "Haven't visited your house in so long I neglected to wear it."

The other Swifts smiled in amused relief, and Mrs. Swift invited him to join them for dessert. Ames, however, declined politely.
