Former NSW Premier and former Federal Minister for Foreign Affairs Bob Carr and his wife Helena were almost inseparable. When she suddenly died, while they were in Vienna on an opera and galleries tour of Europe, Bob was bereft. 

Back in Sydney, he took to walking the streets late at night.

His memoir 'Bring back yesterday' pays tribute to Helena, born to Chinese and Tamil parents in Taiping. Bob Carr reflects on their life together, and on the work and politics that they both, and separately, have been involved in.
