Dr Thorndyke Intervenes by R. Austin Freeman

The products of Polton's labours impressed me as disappointing and hardly worthy of his mechanical ingenuity, consisting of nothing more subtle than an immense coil of rope, rove through two double blocks and forming a long and powerful tackle, a tripod formed of three very stout iron-shod seven-foot poles, and a strong basket such as builders use, furnished with strong rope slings. There was one further item, which was more worthy of its producer; a large electric lamp, fitted with adjustable lenses, and, to judge by the suspension arrangements, designed to throw a powerful beam of parallel rays vertically downwards.

But if Polton's productions were of an unexpected kind, the vehicle in which the Superintendent drove up to our entry was even more so. For, though it bore no outward distinguishing marks, it was an undeniable motor ambulance. However, if less dignified and imposing than the official car, it was a good deal more convenient. The unwieldy tripod, tackle and basket were easily disposed of in its roomy interior, still leaving ample accommodation for me and Polton and the detective sergeant whom Miller had brought as an additional assistant. The Superintendent, himself, was at the steering wheel, and Thorndyke took the seat beside him to give directions as we approached our destination.
