Penicuik residents were rocked when veteran councillor and Midlothian Provost Adam Montgomery died in office in 2018 - months after retaining his seat in the 2017 council election.
The Labour councillor had represented the town for 31 years and been involved in many decisions from new schools to refurbishing Penicuik Town Hall.
The by election, which followed saw SNP councillor Joe Wallace, who had lost his seat in the May election regain his seat and left the three-seat ward with no Labour councillor for the first time in three decades.
