If brother has green ladder arrest brother.新世紀福爾摩斯的綠色梯子：外國人的禁忌superstition：走在梯子底下Walking Under Ladders

為什麼在新世紀福爾摩斯裡面，Sherlock用了華生的手機傳送了以下訊息呢？

If brother has green ladder
arrest brother.
SH

這故事來自於一個福爾摩斯的案子：The Green Ladder

大意是在講Jane的老公Jack意外在家溺死，Jane覺得是Jack的弟弟Keith做的，可是Keith卻有鐵證不在場證明cast iron alibi

不過Keith有犯案動機：如果Jack死了，Keith就可以繼承

但是現場看起來很正常就像是一般喝醉溺死

最後簡而言之就是Keith做的，因為Jack溺死的池塘旁的碎石頭有綠色的油漆，Keith放了一個打開A字的梯子，超級迷信的Jack不願意從正下面經過（迷信經過下面一是死亡的不祥，就像中國人不喜歡四一樣，第二種是褻瀆的意味，跟trinity有關係）

Jack因為繞路還有喝醉酒，就這樣溺死了

Sherlock: Case solved.

所以如果在Keith那發現綠色的梯子，就證明他犯案了

然後就用華生手機發簡訊了

In the light of this的意思：有鑑於此的英文

In the light of this

We can confirm that this apparent suicide closely resembles those of Sir Jeffrey Patterson and James Phillimore. In the light of this, these incidents are now being treated as linked. 

四大字典Collins字典上是這樣說明的：

in the light of something

1. =  considering, because of, taking into account, bearing in mind, in view of, taking into consideration,with knowledge of • In the light of this information, we can now identify a number of issues.
