thought not. Then she was sure not. Finally she ridiculed the idea of minding with scorn.
“If there is width enough,” mused Carrados, spanning the upright critically. “Do you happen to have a wooden foot-rule convenient?”
“Well, to be sure!” exclaimed Miss Chubb, opening a rapid succession of drawers until she produced the required article. “When we did out this room after Mr Ghoosh, there was this very ruler among the things that he hadn’t thought worth taking. This is what you require, sir?”
“Yes,” replied Carrados, accepting it, “I think this is exactly what I require.” It was a common new white-wood rule, such as one might buy at any small stationer’s for a penny. He carelessly took off the width of the upright, reading the figures with a touch; and then continued to run a finger-tip delicately up and down the edges of the instrument.
“Four and seven-eighths,” was his unspoken conclusion.
“I hope it will do, sir.”
“Admirably,” replied Carrados. “But I haven’t reached the end of my requirements yet, Miss Chubb.”
“No, sir?” said the landlady, feeling that it would be a pleasure to oblige so agreeable a gentleman, “what else might there be?”
“Although I can see very little I like to have a light, but not any kind of light. Gas I cannot do with. Do you think that you would be able to find me an oil lamp?”
“Certainly, sir. I got out a very nice brass lamp that I have specially for Mr Ghoosh. He read a good deal of an evening and he preferred a lamp.”
“That is very convenient. I suppose it is large enough to burn for a whole evening?”
“Yes, indeed. And very particular he was always to have it filled every day.”
“A lamp without oil is not very useful,” smiled Carrados, following her towards another room, and absentmindedly slipping the foot-rule into his pocket.
Whatever Parkinson thought of the arrangement of going into second-rate apartments in an obscure street it is to be inferred that his devotion to his master was sufficient to overcome his private emotions as a self-respecting “man.” At all events, as they were approaching the station he asked, and without a trace of feeling, whether there were any orders for him with reference to the proposed migration.
“None, Parkinson,” replied his master. “We must be satisfied with our present quarters.”
“I beg your pardon, sir,” said Parkinson, with some constraint. “I understood that you had taken the rooms for a week certain.”
“I am afraid that Miss Chubb will be under the same impression. Unforeseen circumstances will prevent our going, however. Mr Greatorex must write to-morrow, enclosing a cheque, with my regrets, and adding a penny for this ruler which I seem to have brought away with me. It, at least, is something for the money.”
Parkinson may be excused for not attempting to understand the course of events.
“Here is your train coming in, sir,” he merely said.
“We will let it go and wait for another. Is there a signal at either end of the platform?”
“Yes, sir; at the further end.”
“Let us walk towards it. Are there any of the porters or officials about here?”
“No, sir; none.”
“Take this ruler. I want you to go up the steps—there are steps up the signal, by the way?”
“Yes, sir.”
“I want you to measure the glass of the lamp. Do not go up any higher than is necessary, but if you have to stretch be careful not to mark on the measurement with your nail, although the impulse is a natural one. That has been done already.”
Parkinson looked apprehensively around and about. Fortunately the part was a dark and unfrequented spot and everyone else was moving towards the exit at the other end of the platform. Fortunately, also, the signal was not a high one.
“As near as I can judge on the rounded surface, the glass is four and seven-eighths across,” reported Parkinson.
“Thank you,” replied Carrados, returning the measure to his pocket, “four and seven-eighths is quite near enough. Now we will take the next train back.”
Sunday evening came, and with it Mr Carlyle to The Turrets at the appointed hour. He brought to the situation a mind poised for any eventuality and a trenchant eye. As the time went on and the impenetrable Carrados made no allusion to the case, Carlyle’s manner inclined to a waggish commiseration of his host’s position. Actually, he said little, but the crisp precision of his voice when the path lay open to a remark of any significance left little to be said.
It was not until they had finished dinner and returned to the library that Carrados gave the slightest hint of anything unusual being in the air. His first indication of coming events was to remove the key from the outside to the inside of the door.
“What are you doing, Max?” demanded Mr Carlyle, his curiosity overcoming the indirect attitude.
“You have been very entertaining, Louis,” replied his friend, “but Parkinson should be back very soon now and it is as well to be prepared. Do you happen to carry a revolver?”
“Not when I come to dine with you, Max,” replied Carlyle, with all the aplomb he could muster. “Is it usual?”
Carrados smiled affectionately at his guest’s agile recovery and touched the secret spring of a drawer in an antique bureau by his side. The little hidden receptacle shot smoothly out, disclosing a pair of dull-blued pistols.
“To-night, at all events, it might be prudent,” he replied, handing one to Carlyle and putting the other into his own pocket. “Our man may be here at any minute, and we do not know in what temper he will come.”
“Our man!” exclaimed Carlyle, craning forward in excitement. “Max! you don’t mean to say that you have got Mead to admit it?”
“No one has admitted it,” said Carrados. “And it is not Mead.”
“Not Mead…. Do you mean that Hutchins——?”
“Neither Mead nor Hutchins. The man who tampered with the signal—for Hutchins was right and a green light was exhibited—is a young Indian from Bengal. His name is Drishna and he lives at Swanstead.”
Mr Carlyle stared at his friend between sheer surprise and blank incredulity.
“You really mean this, Carrados?” he said.
“My fatal reputation for humour!” smiled Carrados. “If I am wrong, Louis, the next hour will expose it.”
“But why—why—why? The colossal villainy, the unparalleled audacity!” Mr Carlyle lost himself among incredulous superlatives and could only stare.
“Chiefly to get himself out of
