A servant in livery got off the box and pulled the chain of the bell.
It was Michel's business to open the gate, but Michel was away, as we know.

Amelie and Charlotte probably counted on him, for the bell was rung three times before any one answered it.

At last the maid appeared at the head of the stairs calling Michel.

Michel made no reply.

Finally, protected by the locked gates, Charlotte ventured to approach them.
