Mr Falk is looking for you

Many years ago I lived at my parents home together with my husband and daughter. My husband got a phone call but he was not at home so my father answered the phone call. It was a security company who my husband worked with and they wanted to speak to him. When my husband came home my dizzy father said: Someone phoned you. It was a Mr Falk. My husband wondered if Mr Falk had left a phone number...but my father replied No. We wondered who this mysterious Mr Falk was as it for sure was not Mr "Columbo". In the end the security company Falck told my husband that they had looked for him and then everything fell into place. Really dizzy father-in-law!
