Long Day's Journey into Night by Eugene O'Neill (1956)

By nightfall a foghorn is moaning out on the Sound, and inside the summer house the four Tyrones have talked their way back through every betrayal they have ever handed one another. Mary drifts upstairs and returns changed, the morphine pulling her out of reach while her husband and sons pretend not to see; James, the matinee idol who traded his talent for a sure thing, counts the cost of every lamp left burning; Jamie drinks; Edmund, the youngest, coughs and waits to hear how bad his lungs really are. Eugene O'Neill set down his own family here, sealed the manuscript, and asked that it never be staged in his lifetime. What binds these four is not cruelty but love so wounded it can only come out as blame. The fog they each long for is the time before the harm was done, and the night the title keeps promising is what is left when even that fog will not hold.
