The Man Who Went Up In Smoke by Maj Sjöwall, Per Wahlöö

duty, so he rose, put the map and his passport into his hip pocket and went down to inspect the luggage.
    The porter was a somewhat stout, elderly man, friendly, dignified and admirably intelligible.
    No, no one had phoned Mr. Matsson while Mr. Matsson was still in the hotel. Later, when Mr. Matsson had left, there had been several calls. They had been repeated the following days. Was it the same person who had phoned? No, several different people—the operator at the board was sure of that. Men? Both men and women, at least one woman. Had the people who phoned left any messages or telephone numbers? No, they had left no messages. They hadn't given their telephone numbers either. Later there had been calls from Stockholm and from the Swedish Embassy. Then, however, both messages and telephone numbers had been left. They were still here. Would Mr. Beck like to see them? No, Mr. Beck would not like to see them.
    The luggage was indeed to be found in a room behind the reception desk. It was very easily inspected. A portable typewriter of the standard make Erika and a yellowish-brown pigskin suitcase with a strap around it. A calling card was fitted into the leather label dangling from the handle. Alf Matsson, Reporter, Fleminggatan 34, Stockholm K. The key was in the lock.
    Martin Beck took the typewriter out of its case and studied it for a long time. Having come to the conclusion that it was a portable typewriter of the Erika make, he went over to the suitcase.
    The bag appeared neatly and carefully packed, but all the same he had a feeling that someone with a practiced hand had been through it and put everything back into place. The contents consisted of a checked shirt, a brown sport shirt, a white poplin shirt with the laundry band still around it, a pair of freshly pressed light-blue trousers, a kind of blue cardigan, three handkerchiefs, four pairs of socks, two pairs of colored shorts, a fishnet undershirt and a pair of light-brown suede shoes. Everything was clean. In addition, a shaving kit, a sheaf of typing paper, a typewriter eraser, an electric razor, a novel and a dark-blue plastic wallet of the kind that travel agencies usually give away free and that aren't big enough for the tickets. In the shaving kit were shaving lotion, talcum powder, a cake of soap still in its wrapper, a tube of toothpaste that had been opened, a toothbrush, a bottle of mouthwash, a box of aspirin and a pack of contraceptives. In the dark-blue plastic wallet were $1500 in $20 bills and six Swedish 100-kronor notes. An astonishingly large sum for traveling money, but Alf Matsson seemed to be accustomed to doing things in a grand manner.
    Martin Beck put everything back as nicely and neatly as possible and returned to the reception desk. It was noon and high time to go out. As he still didn't know what he should do, he might at least do it out in the fresh air—for instance, in the sun on the quay. He took his room key out of his pocket and looked at it. It looked just as old, as venerable and as solid as the hotel itself. He put it down on the desk. The porter at once reached out his hand for the key.
    'That's a spare key, isn't it?"
    'I don't understand," said the porter.
    'I thought that the previous guest took the key with him."
    'Yes, that's right. But we got the key back the next day."
    'Got it back? Who from?"
    'From the police, sir."
    'From the police? Which police?"
    The porter shrugged his shoulders in bewilderment.
    'From the ordinary police, of course. Who else? A policeman handed in the key to the doorman. Mr. Matsson must have dropped it somewhere.'"
    'Where?"
    'I'm afraid I don't know, 
sir
."
    Martin Beck asked one more question.
    'Has anyone else besides me gone through Mr. Matsson's luggage?"
    The porter hesitated for a moment before answering.
    'I don't think so, sir."
    Martin Beck went through the revolving door. The man with the gray mustache and a visored cap was standing in the shade beneath the balcony, perfectly
