When the order for Mossotti to go to the police headquarters to be questioned arrived to Brera Observatoire, on the 24 March 1823, he was not there. He had left to go to Carpignano on 16 March, telling the observatoire that he had to recover from a seasonal illness by spending a few days in the fresh countryside air. The passport he used to cross the Piedmont border was the same one he had used on the occasion of the Christmas holidays, so it was an expired one; nonetheless he managed to leave Lombardy without problems. He was expected back to work on the 24 March. According to M10 and M24 he came back some day around the 24 March, stayed for a couple of hours in the Observatoire without meeting anybody, picked up a few books and clothes and left again. There is no mention about this short visit to Milan in M25 (by de Cesaris, who also wrote M10 and M24). Before the end of March a friend of Mossotti came from Carpignano to the Observatoire to inform the Astronomers that Mossotti hadn't recovered yet and that he needed some more time. On 1 April Mossotti sent a letter to de Cesaris asking formally for more time off, enclosing a medical certificate. On 2 May the Government sent a short letter to Brera Observatoire asking news about Mossotti, saying that the only information the Government had was that Mossotti left Lombardy without a valid passport, went to Novara and then to Geneva. The reply by Brera (M10, of which M24 is the rough copy) dates 3 May and among other things, de Cesaris protested not knowing anything about Geneva. On 6 May de Cesaris sent another letter to the Government (M25), enclosing the medical certificate Mossotti had sent on the 1 April. The Government replied on 16 May saying that the medical certificate was without vidimation and date, and could not therefore be taken into consideration. The news of his escapade travelled rapidly throughout Italy. On 31 May 1823 Giuseppe Bianchi wrote to Giuseppe Piola ``Why didn't you tell me anything about the rumours concerning Mossotti's escape from Milan?", but the Government could not take any action against Mossotti because the whole thing ``remained in the limits of a simple suspicion".
