It was only Saturday, the day of the murder was remarkable enough to fix people's memories, and up till then there had not been time to start a proper investigation.
He arranged for five of the most experienced detectives in the secret service to be sent to Bougival, supplied with photographs of the prisoner.

They were to scour the entire country between Rueil and La Jonchere, to inquire everywhere, and make the most minute investigations.

The photographs would greatly aid their efforts.

They had orders to show them everywhere and to everybody and even to leave a dozen about the neighbourhood, as they were furnished with a sufficient number to do so.

It was impossible, that, on an evening when so many people were about, no one had noticed the original of the portrait either at the railway station at Rueil or upon one of the roads which lead to La Jonchere, the high road, and the path by the river.
These arrangements made, the investigating magistrate proceeded to the Palais de Justice, and sent for Albert.
