The following is an extract from Frankenstein by Mary Shelley. I'm wondering whether the word "behind" is equal to "ahead" in 21st-century English in this context.
Justine died; she rested; and I was alive. The blood flowed freely in my veins, but a weight of despair and remorse pressed on my heart, which nothing could remove. Sleep fled from my eyes; I wanderedlike an evil spirit, for I had committed deeds of mischief beyond description horrible, and more, much more (I persuaded myself), was yet behind. Yet my heart overflowed with kindness, and the love of virtue.
