Markus was captain of the winning team at Monte Carlo in 1954 against formidable opposition from all over the world: her team-mates were Konstam, Dodds, Reese, Schapiro and "Plum" Meredith. After their victory, Reese and Konstam decided to ask the British selectors to include Markus in their team for the European championships at Montreux that year, but the selectors did not choose her for either the Open or Ladies teams (the reasons are not known). The Open team played with the lesser player Jordanis Pavlides in her place, because their other regular team members such as Pedro Juan were not available. That team won the European and later the Bermuda Bowl trophies. In effect, a bizarre decision by the selectors cost her the European and World teams championships in the Open category. She had other disappointments; this was not the only time she was dropped from the Ladies' team, often when her results were quite outstanding.
