片尾曲即是剧透

《熱海の捜査官》的精妙就在于每个不起眼的细节都可能是指引真相的关键所在。
我一直都只太关心片尾曲的音乐、椎名林檎的歌声，同每一集结束时高潮完美的合衬，而忽略了最震撼最紧要的歌词。

片尾曲Title《天国へようこそ》（欢迎来到天国）正好与南热海入口那个欢迎招牌“南熱海は天国かも（南热海也许是天国）”相呼应。

there is one truth
if you say
still I'm dreaming,
you're acting in a play you call your life
the sketch of flowers on paper
can you smell them
well I would rather bloom for eternity
don't talk to me
I'm gonna suck and drink your life
right from you
no life in me
I've got no time for changeless things
and useless things

which one is the real face of the sky
day or night
how do you think
oh, I suppose it's both
it's contradicting, the nature of existence
somewhere I must go without delay

goodbye my sunshine
goodbye my darkest day
cause I have just wasted my life away
I'm more dead than alive
hello, I'm gonna suck and drink your life
right from you
don't come near me
now it is time to recognize
when you cross the bar
I am dead

歌词的最后一句，即对真相一击即中：
when you cross the bar
I am dead
