《福尔摩斯：基本演绎法第2季》讲述了福尔摩斯曾是英国著名的咨询侦探，华生曾是事业有成的外科医生，二人因故在纽约相识，开始合作探案的故事。福尔摩斯和华生来到伦敦调查一起尚未侦破的悬案，同时追踪一名往日的同事。与此同时，福尔摩斯与素来关系疏远的兄弟Mycroft重聚，但Mycroft似乎隐藏了一些秘密。本集的结尾音乐响起，夏洛克和他的哥哥之间的误解终于没有了，他在这时也理解了他的哥哥。

这首歌由Tunng这支乐队演唱，他们被人们称作电子民谣乐队，一直走的是不愠不火的路线，他们可能缺少成为大牌乐队的气质，但却有毫不做作的单纯活泼。

【歌词】

Through smoke and sleight of hand

He does what he can

He gets on by on his own

Follow him on the street

Silent on his feet

Diamonds fall on his door

The underground man

Hiding where he can

Raises his feet to the fire

Forgets as he sleeps

Under the midday sun

He lets his loneliness tire

After your heels

With calling all around you

Whispering near

You take a full scream with you

After your heels

With calling all around you

Whispering near

You take a full scream with you

Follow, follow, follow, follow

Follow, follow, he said

Follow, follow, follow, follow

Follow, follow, he said

The faces he scams

Through smoke and sleight of hand

You have to see it to believe

Take what you can

The camouflaged man

Like him you look right through

He covers up his eyes

And like the time he buys

You won’t find him again

After your heels

With calling all around you

Whispering near

You take a full scream with you

If you miss him

A word is hard to see through

Call for your attention

Your heart is hard to value

After your heels

With calling all around you

Whispering near

You take a full scream with you
