There is some information here, not sure how valid any of this is. These links gives the name of agent and a discussion of the plane's identity.

A slightly different version of events is reported here.
In the book "MI6", by Keith Jeffery (page 388) , it says that agent "Henri Leenaerts" was flown in on 17/18 August 1940 but the
Lysander which was carrying him was unable to land and was lost on the return flight, killing the pilot and the agent.
