Marlow's poor away form failed to reverse at Bedford Town as the home side fought back from a 1-2 deficit to score twice more and take the points in their late charge for a play-off place.
Having taken the lead with a flicked headed from a dead ball situation in the 51st minute through Bradley Woods-Garness the Blues levelled some 15 minutes later when Kelvin Bossman powered in a header from a driven corner from brother Allen.
The Eagles were then stunned when the visitors took the lead 5 minutes later with central defender Tommy Hull turning a dangerous cross from Kamaron English into his own net to see the Blues take the lead. However this did not last long as just 2 minutes later Woods-Garness netted again to level the scores and 2 minutes after that Paul Benson rose unchallenged to head in what proved to be the winner.
