Suzuki-san and his "wife" met the Kawamura family at Narita Airport when they returned from the United States. The only jarring note in the reunion was that Suzuki-san's woman-of-the-moment, smiling, looking very attentive, was the waitress from the Tokyo Lawn Tennis Club.
部下のSuzuki-sanの "wife" に ""が付いているのは、話の中でこれまで独身だったからでしょう。
相手の女性との関係は事件を捜査しているときに次ぎのように伏線がありました。

Kawamura looked at his assistant's shaved, bullet head.
"You don't realize," added Suzuki-san, "but many ladies like my style. Kojak," he said, referring to an American television show popular in Japan.
Kojak、懐かしいですね、昔テレビで見ました。ところで "woman-of-the-moment" は "spur-of-the-moment" を連想させるので、一目ぼれの意味がある様な気がしますがどうでしょうか？
