'A Case of Lemmings' by Philip Broadley

Paris, France: while driving his car, an Interpol agent deliberately takes his hands off the steering wheel, allowing to the vehicle to plummet over the edge of a cliff. When another agent jumps off an express train, and a third throws himself into the path of an oncoming car, Interpol call on Nemesis to help discover why their agents are intent on committing suicide. Craig, Richard and Sharon learn that each of the agents had brought charges against the same Mafia leader, Del Marco. But when Craig sets himself up as a target for the Mafia, Sharron and Richard must come to his aid when he also develops a suicidal urge...
