Honoré Lechasseur was an American from New Orleans, Louisiana, who came to Europe whilst serving in the US Army during World War II. His platoon were moving through France. They became lost and ended up in Belgium, where they found a farmhouse that had recently been abandoned by German soldiers. The group settled down to enjoy a stash of alcohol that had been left behind and Honoré's Lieutenant began to play a piano. It had been booby trapped with explosives and the lieutenant was killed.
Honoré was injured in the explosion. Army medics told him he would never walk again. He also suffered psychological injuries, made worse by the knowledge that of his entire platoon, Honoré was the only other person who could play the piano. If his lieutenant had not been been killed, it might have been Honoré. He was moved to hospital in England in 1943, where he began to recover the use of his legs. He also began to develop an ability to see people's pasts and futures. He learnt later this was called time sensitivity.
Whilst in hospital, Honoré was treated by a small, bearded, Scottish doctor, who helped him recover partially. Honoré left the hospital and relocated to Shoreditch in London, where he began working as a black market "spiv" — although he preferred the term "fixer".
In 1949, Honoré was hired by a woman posing as Emily Blandish to find her "husband", the Doctor. During the course of his investigations, Honoré met a young amnesiac woman dubbed "the girl in the pink pyjamas" by the press. Together they helped save the Cabinet of Light from a Nazi cult desperate to possess it for their own ends. He also helped the girl to remember her real name: Emily Blandish.

Following this adventure, Emily and Honoré kept in touch and built a strong relationship. It was not until they both happened to spot the same man at the same time and wonder where he had come from, however, that they realised that Emily was a time sensitive. They travelled in time to an alternative 1984, where they worked out how to get back to their own time. Ultimately they did, whilst also ensuring that the future they had witnessed never came about.

Honoré and Emily eventually came to understand how they had travelled through time, and became so practised at it that they could travel at will to a chosen date and time. They had adventures together, in which they fought the Fendahl (PROSE: Deus Le Volt) and gained the enmity of a mysterious time-travelling cult. (PROSE: The Severed Man)
Honoré was moral and prided himself on never having swindled any of his customers. He developed from struggling to understand and live with his abilities, to embracing them through his platonic relationship with Emily Blandish. Through his career with her, he progressed from using alcohol on a regular basis as a "painkiller" to becoming a teetotaler. (PROSE: The Cabinet of Light et al)
