“What is the object of this circle of misery,and violence,and fear?It must have a purpose,or our universe has no meaning and that is unthinkable . But what purpose?That is humanity’s great problem for which reasons so far there's no answer”这是整个剧集的最后一段话,二刷完成了。以前看福尔摩斯,主要是着重缜密思维和神奇推理,然而更是人性弱点和丑恶的镜鉴,尤其是《讹诈庄家》《单身贵族》和这最后一集《硬纸盒子》表现得尤其明显。
