Robert A. Heinlein. The door into summer (№ 90384)

But in my heart reigned winter.
I was healthy (except for the mighty hangover). I needed a few days to thirty years - I was in the juice. Neither the police nor the intelligence agencies nor angry husbands after me do not chase. The only thing that bothered me was it's incurable forgetfulness. But in my heart it was winter and I was looking for door into Summer.
