Under the chalk
"Didn't mean to startle you." He offered his hand, dry and strong under the chalk. "I'm Paul Collins, your pilot. Recognized you on the passenger roster."
—Joe Haldeman, Marsbound (2008)
UPDATE: "My" Paul Collins has discovered the solution: "...It's a shout-out to the Australian sci-fi Paul Collins!"
