Mr. Spiegle.
Owner of Spiegle's Jewelry Store, one of the jewelry stores targeted by the League of Bald-Headed Men, KAOS's smuggling unit.
League members Winters and Sommers try to force Mr. Spiegle to hand over the famed Morris Diamond but he sells it to Maxwell Smart, who happens into the store shopping for an engagement ring for 99, for the low sum of $80.00 rather than let it fall into their hands.
After Max leaves, the bald-headed agents tie Mr. Spiegle up and resume their efforts to get him to reveal the hiding place of the diamond. He refuses but becomes rattled when Max continually returns, leaves and returns again to ask questions about his purchase.
Sadly, Mr. Spiegle is last seen begging the KAOS men to kill him before Max can return again.
