into a little bag about three inches in diameter and two feet six long. Both ends were sewn up tightly, but near one of them the canvas had been gashed with a knife. Vandam held his hand under the hole and shook the little tube. Some grains of sand fell out.
‘Just so,’ he thought. ‘Sandbagged in that shed. But what in all this earthly world was done with the hammer?’ He turned to his subordinate. ‘Here, Clarke, bring along that hammer. But don’t touch the clean part of the handle; there might be a fingerprint on it somewhere.’
Postponing consideration of his treasure-trove, Vandam continued his search. He climbed the wall and found himself in the lane leading into Craven Street. But its surface was hard, and though he examined it carefully from end to end, he could find no trace of anyone having passed.
Having sent Clarke for an acetylene lamp, Vandam returned to the potting shed and began one of his painstaking examinations. Every inch of the floor and shelf was scrutinised, every grain of the little heaps of soil which lay scattered about was sifted through his fingers. But his discoveries were negligible. One thing only he found, and that a triviality. The ashes in the corner were the remains of newspapers. Beyond that there was nothing.
He stood motionless, pondering over the tragic business.
First of all he wondered at what time the murder had taken place. Before 11.10 on the previous evening obviously, because the body had been struck by a train at that hour. But how much before? The murderer would want some margin of time to get the body into position and to allow for unexpected checks. But he would make this margin as short as possible, to reduce to a minimum the risk of the remains being found before the train passed. It seemed to Vandam that the meeting in the shed must have taken place about half-past ten or a little later. This, of course, was guesswork, but he could hardly picture even so cold-blooded a criminal as this ruffian must be, despatching his victim at an early hour in the evening and then sitting in the shed with the corpse, waiting until it should be time to drag it down to the line.
A further point struck him. It would, of course, be dark at this hour. Would a light not therefore have been necessary in the shed? The burning of the papers, if that had been done at the same time, would certainly have made a light. What chance would there be of that light having been seen.
Quite a good chance, Vandam decided. Though the majority of the evening visitors to the park kept down at the other end near the electric arcs and the bandstand, isolated strollers might penetrate as far as the gardens. And the screen of evergreens, though thick, could not be depended on to prevent a light showing through. Therefore, if the affair was to be kept secret before those papers could have been burned or a light used, the door must have been shut. There was, of course, no window.
Hoskins had opened the door that morning from the outside, but he hadn’t touched the inside. The murderer’s fingerprints should therefore be intact.
Vandam brought his lamp to the back of the door, and he experienced a shock of real disappointment when he saw that the woodwork was too rough to receive impressions. He would get no help there.
He felt slightly overwhelmed as he thought of the variety of problems which awaited solution. Who was guilty of the murder? What was the motive? Was more than one person involved? How had Smith been lured to the shed? What was the meaning of the sweeping of the floor and the burning of the newspapers? What had been done with the hammer? These were but a few of the salient points, and on not one of them had Vandam the slightest suggestion to offer.
But he realised that this was the position of affairs at the beginning of every inquiry, and he was by no means downhearted. Rather was he pleased that what would undoubtedly prove one of the most thrilling and important cases of the year had fallen to his lot.
He did not see that he could learn anything more on the ground, and his next business must undoubtedly be to find out as much as possible of Smith’s life and personality. No doubt he would thus come across some clue which would lead him to the solution he desired.
Having sent Clarke to get a padlock put on the door of the shed, he returned to headquarters. There he tested the hammer for fingerprints, but unfortunately here again without result. Next he returned to the station, made a further examination of the murdered man’s clothes, took prints from the dead fingers, and lastly, having set in order the facts he had learnt, went in and had a long interview with his Chief.
INSPECTOR VANDAM, hot on a new case, was a very different person from the same man engaged in routine police work in his office. Not that he was at any time slack or lazy; he was naturally too efficient and hardworking for that. But the interest of a new mystery stimulated him to an enthusiasm which rendered him careless of rest or even food, and drove him on with a tireless energy until he had either found a solution of his problems or satisfied himself that none was obtainable.
In the present case, though it was considerably after his usual lunch hour when he left his Chief’s office, he contented himself with a five-minute pause for a sandwich and a cup of coffee in a restaurant before starting the next phase of his investigation. He never drank alcohol, saying that it stupefied him, while hot coffee, he held, stimulated his brain to keener and more incisive thought. Many a criminal was brought to justice, he used to claim, as a result of his coffee habit.
He had decided that his first business must be a call at Messrs. Hope Bros. store in Mees Street. The knowledge gained since Sergeant Clarke had been there earlier in the day necessitated inquiries of a different kind to those already made, and he entered the great building and asked for the manager in the hope and belief that before he came out he would have learned at least the direction in which his subsequent inquiries should tend.
Mr Crawley, it seemed, was again out, and, like the sergeant, he was received by the assistant manager, Mr Hurst.
‘I am sorry to trouble you again about this affair,’ Vandam began, when he had introduced himself and stated the subject of his visit, ‘but our people at headquarters are not quite satisfied that we have really got to the bottom of it. They fear it may not have been the accident it looked like at first sight.’
The assistant manager stared. Vandam, whose golden rule was to give nothing away and distrust everybody, watched him keenly and unobtrusively. But there was neither embarrassment nor undue interest in the man’s manner as he exclaimed:
‘Now just what do you mean by that, Inspector?’
Vandam leaned forward and spoke confidentially.
‘There’s a suggestion of suicide.’
Mr Hurst whistled.
‘So that’s the idea,’ he returned. ‘What makes you think that?’
‘We can’t see what else would have taken him to the railway at that time.’
‘Not very conclusive, is it? That your only reason?’
‘Not exactly,’ Vandam answered slowly. ‘There are others. But what do you think of the suggestion?’
Mr Hurst moved impatiently.
‘I don’t think much of it,’ he declared. ‘Smith wasn’t the suicide kind, not by
