回到韦尔贝克街,沿着右手边的前进的第一个路口向右拐走上女王安妮街,沿着左手边向前走,横穿魏宝街,可以看到哈利街(Harley Street)的路口。右手边的哈利街6号是穆尔·阿加医生的咨询室,正是在这个地方,医生命令老福一定要外出度假一段时间,否则他的身体状况会彻底崩溃。老福随即领着华生去了康沃尔郡,在那里幸运地遇上新一起谋杀案。
“那是1897年春。福尔摩斯日夜操劳,他那铁打的身体渐渐有些支持不住,又加上他自己平时不够注意,健康情况开始恶化。那年三月,住在哈利街的穆尔·阿加医生——关于把她介绍给福尔摩斯的戏剧性清洁当改日再谈——明确命令我们这位私家侦探放下他的所有案件,彻底休息,如果他不想完全垮掉的话。”——《魔鬼之足》
It was, then, in the spring of the year 1897 that Holmes’s iron constitution showed some symptoms of giving way in the face of constant hard work of a most exacting kind, aggravated, perhaps, by occasional indiscretions of his own. In March of that year Dr Moore Agar, of Harley Street, whose dramatic introduction to Holmes I may someday recount, gave positive injunctions that that the famous private agent lay aside all his cases and surrender himself to complete rest if he wished to avert an absolute breakdown.
