Who is July and Xleo from Death in the Long Grass and what is their importance?

July is an older African villager, and Xleo is his sole surviving son. One night, July watches Xleo walk home across the village when he sees a huge male leopard seize Xleo in a killing grip and haul him away into the nighttime. July cries out and searches for the boy—but he is gone.

Capstick, his tracker Debalo, and his gunbearer Simone, happen to be in town the evening of the attack and on the next morning, they hunt the leopard. On the evening after Xleo is killed, Capstick waits near Xleo's decomposing body, hoping for a shot at the man-eating leopard. The leopard does appear but turns the tables on Capstick and begins to stalk him. Capstick finally gains the upper hand, shooting the leopard. Xleo's body is recovered, and his remains are delivered back to July.
