Some wounds are deep, while some are from barely minor blows.
Some stabs seem to have been inflicted by right-handers and others by a left-hander.
Before long, Poirot has 12 suspects - each with a motive, but all with convincing alibis - and a stalemate. It is only when he puts all the facts together that he arrives at an unusual conclusion: all of them did it.
All of the 12 suspects were extracting revenge on behalf of a three-year-old girl who was kidnapped and killed by the gangster - the stab victim on the Orient Express.
If one were to ask, 'Who killed Air India?' the answer would have to be something similar - perhaps all of them.
Further, if we were to ask if it was murder or suicide, the answer would have to be that it was both.
