Who is Hector Lepodise, Dr. Maketsi from The No. 1 Ladies' Detective Agency and what is their importance?

Hector Lepodise and Dr. Maketsi, the agency's two male clients, are both old family friends, and as such have earned Mma Ramotswe's respect and compassion, partly because of their loyalty to her father and partly because they share characteristics with him. Their initial resistance to her independence, tempered by a general good heartedness and open mindedness, becomes transformed when they see the work and compassion she's capable of.
